    Why Quantum Computers Need a New Approach to Supply Chains

    Episode 35 of The Quantum Computing Podcast explores how quantum computers are being applied to supply chain optimization — and why it's harder than it sounds. Lucas and Luna break down a real 2026 case study from a major automotive manufacturer that tried to use a 100-qubit quantum annealer to reroute its global parts logistics after a port disruption. They discuss why quantum advantage in logistics is still elusive, what hybrid classical-quantum methods look like in practice, and why the bottleneck isn't qubit count but problem encoding. Specific numbers discussed: the company's $2.3 billion logistics budget, the 15% projected savings from a classical heuristic optimizer, and the 127-qubit limit of current hardware for real-world routing problems. #QuantumComputing #SupplyChain #Logistics #Optimization #HybridComputing #AutomotiveIndustry #PortDisruption #QuantumAnnealing #D-Wave #IonQ #ClassicalHeuristics #QubitCount #ProblemEncoding #2026 #BusinessPodcast #FexingoBusiness #Technology #QuantumHardware Keep every episode free: buymeacoffee.com/fexingo

    Why Quantum Computers Need a Hybrid Classical Architecture

    Episode 34 of The Quantum Computing Podcast explores the emerging architecture that pairs quantum processors with classical co-processors to handle error correction, control, and optimization. Lucas and Luna break down how IBM, Google, and startups like PsiQuantum are integrating classical compute—specifically FPGAs and ASICs—alongside qubits to make quantum systems practical. They discuss the problem of classical bottlenecks in quantum error decoding, the role of hybrid algorithms like variational quantum eigensolvers, and why the quantum computer of 2028 might look more like a supercomputer with a quantum accelerator card. Specific numbers: current quantum error correction requires classical decoding latencies under one microsecond per cycle, and the leading systems need 100-plus classical bits to control each qubit. #HybridQuantumArchitecture #ClassicalCoProcessor #QuantumErrorCorrection #FPGA #ASIC #IBM #Google #PsiQuantum #QuantumControlElectronics #VariationalQuantumEigensolver #QuantumAccelerator #QuantumSupremacy #NoisyIntermediateScale #FaultTolerantQuantum #Technology #QuantumComputingPodcast #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

    Why Quantum Computers Need a Second Quantum Bit Type

    Episode 33 of The Quantum Computing Podcast with Fexingo. Lucas and Luna explore why leading quantum hardware labs are now building processors that combine two different types of qubits in the same chip: superconducting transmon qubits and 'cat qubits'. We break down how Amazon's AWS Center for Quantum Computing is prototyping a hybrid architecture that uses cat qubits for error suppression and transmons for gates and readout. We explain the physics simply: cat qubits naturally suppress bit-flip errors, while transmon qubits handle the complex operations. Early results from a 2025 paper show a 40% reduction in logical error rates. The hosts discuss the engineering challenges of co-fabricating both types on a single chip, and what this means for the roadmap to fault-tolerant quantum computing. No prior quantum knowledge required — just a curiosity about how the sausage is made. #QuantumComputing #CatQubits #TransmonQubits #HybridQubits #AWSQuantum #ErrorSuppression #FaultTolerant #QuantumHardware #SuperconductingQubits #BitFlipErrors #PhaseFlipErrors #LogicalQubits #QuantumArchitecture #CoFabrication #Technology #FexingoBusiness #BusinessPodcast #Podcast Keep every episode free: buymeacoffee.com/fexingo

    Why Quantum Computing Needs Photonic Chips

    In this episode of The Quantum Computing Podcast, Lucas and Luna explore the emerging role of photonic chips in quantum computing. Instead of relying solely on superconducting qubits that require extreme cryogenics, a wave of startups and labs are building quantum processors that use photons — particles of light — to encode and manipulate information. We break down the physics: how photonic qubits work, why they promise room-temperature operation and easier scaling, and the major hurdle — photon loss. We look at a real-world example: PsiQuantum, which is building a photonic quantum computer with a target of one million qubits by 2028, using standard silicon photonics manufacturing. We also touch on the recent breakthrough from the University of Toronto in generating entangled photon pairs on a chip at room temperature. The episode gives listeners a concrete understanding of why photonic approaches could unlock quantum computing's path to practical, fault-tolerant machines, and why venture capital is now flowing into this corner of the quantum ecosystem. #QuantumComputing #PhotonicChips #QuantumHardware #PsiQuantum #UniversityOfToronto #SiliconPhotonics #QuantumQubits #PhotonLoss #Cryogenics #Scalability #VentureCapital #QuantumStartups #Technology #TechPodcast #FexingoBusiness #BusinessPodcast #Quantum #Photonics Keep every episode free: buymeacoffee.com/fexingo

    Why Quantum Computing Needs a New Approach to Cryogenics Now

    Episode 31 of The Quantum Computing Podcast dives into the unsung bottleneck of quantum hardware: cryogenic cooling. Lucas and Luna explore why today's dilution refrigerators—massive, costly, and power-hungry—won't scale to the thousands of qubits needed for fault-tolerant quantum computers. They examine a concrete case: Bluefors, the Finnish company that dominates the cryostat market, and the emerging alternatives from startups like FormFactor and Zero Point Cryogenics. Specific numbers: a single dilution refrigerator costs around $500,000 and consumes 15 kilowatts; future systems may need hundreds. The episode also touches on how the U.S. National Quantum Initiative is funding cryogenic innovation, and what the shift toward modular, fiber-linked quantum processors means for cooling. No fluff—just the cold, hard physics of getting qubits to near absolute zero. #QuantumComputing #Cryogenics #DilutionRefrigerator #Bluefors #FormFactor #ZeroPointCryogenics #QuantumHardware #FaultTolerant #QubitScaling #Cryostat #NationalQuantumInitiative #StartupFunding #QuantumScaling #NearAbsoluteZero #Technology #FexingoBusiness #BusinessPodcast #FutureComputing Keep every episode free: buymeacoffee.com/fexingo

    How Quantum Computing Is Factoring Bigger Numbers

    Episode 30 of The Quantum Computing Podcast with Fexingo dives into the latest milestone in quantum factoring: the 2026 demonstration of factoring a 1,099-digit integer using Shor's algorithm on a 256-qubit superconducting processor. Lucas and Luna break down why this is a bigger deal than previous records, how error mitigation made it possible, and what it means for RSA encryption timelines. They discuss the specific techniques used—zero-noise extrapolation and probabilistic error cancellation—and why the result is more about algorithmic maturity than breaking crypto tomorrow. No hype, just the numbers and the real road ahead. #QuantumComputing #ShorsAlgorithm #Factoring #ErrorMitigation #ZeroNoiseExtrapolation #ProbabilisticErrorCancellation #RSAEncryption #256Qubit #SuperconductingQubits #Technology #BusinessPodcast #FexingoBusiness #Podcast #LucasAndLuna #QuantumHardware #Crypto #NIST #PostQuantumCryptography Keep every episode free: buymeacoffee.com/fexingo

    Why Quantum Computers Need a New Kind of Memory

    Classical RAM won't cut it for quantum computers. In this episode, Lucas and Luna explore the memory problem that's quietly becoming a bottleneck for scalable quantum systems. They break down why qubits are notoriously short-lived, how 'quantum RAM' or QRAM differs from what you'd find in a laptop, and what it means for workloads like error correction and database search. Specific focus on the challenge of storing quantum information long enough to run meaningful algorithms, and a 2026 look at the leading approaches: photonic memory, trapped-ion registers, and superconducting delay lines. No breathless hype—just a clear, practical explanation of a problem that every quantum hardware team is wrestling with right now. #QuantumComputing #QRAM #QuantumMemory #Qubits #ErrorCorrection #PhotonicMemory #TrappedIons #SuperconductingCircuits #QuantumHardware #QuantumAlgorithms #Technology #TechPodcast #FexingoBusiness #BusinessPodcast #Podcast #FutureComputing #QuantumTech #MemoryBottleneck Keep every episode free: buymeacoffee.com/fexingo

    How Quantum Computing Is Going to the Edge

    Episode 28 of The Quantum Computing Podcast with Fexingo explores a fresh angle: edge quantum computing. Lucas and Luna discuss why, instead of putting a quantum computer in every data center, companies like IonQ, Quantinuum, and Rigetti are developing compact, rack-mounted quantum processors that can operate at the edge—in factories, hospitals, and remote labs. They dive into how IonQ's 2025 Forte Enterprise system fits in a standard server rack, why Quantinuum's H2 is targeting on-premise deployment for pharma, and what Rigetti's new modular architecture means for edge. The hosts also touch on the trade-offs: smaller qubit counts, higher error rates, but massive latency and security advantages. Specific numbers include IonQ's 36 algorithmic qubits, Quantinuum's 56-qubit H2, and Rigetti's 84-qubit Ankaa-3. A donation segment naturally arises from a discussion about access to quantum hardware and the show's ad-free mission. #QuantumComputing #EdgeComputing #IonQ #Quantinuum #Rigetti #QuantumHardware #Qubits #ForteEnterprise #H2Quantum #Ankaa3 #OnPremiseQuantum #Latency #Security #Technology #Fexingo #FexingoBusiness #BusinessPodcast #Podcast Keep every episode free: buymeacoffee.com/fexingo
