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
