The Post-Quantum World

The “Constellation Platform” is revolutionizing the path to fault-tolerant quantum computing. Rather than relying on traditional state vector simulations that hit a wall at 50 qubits, this platform from Quantum Elements uses a breakthrough method, stochastic compression, to create realistic digital twins of quantum hardware at scale. This approach allows developers to simulate the complex time evolution of a system, including specific noise models such as crosstalk and decoherence, without the high cost of running thousands of shots on physical QPUs.   
Host Konstantinos Karagiannis sits down with Izhar Medalsy, co-founder and CEO of Quantum Elements, to also explore the cutting-edge intersection of AI and quantum engineering, highlighting a “quantum copilot” in Constellation powered by Claude. This AI-native platform doesn't just help write context-specific code; it also acts as a virtual supervisor that can troubleshoot failed experiments by comparing real-world results with first-principles simulations. Whether you are a professional looking to optimize algorithms through advanced error suppression or a researcher seeking a hardware-agnostic layer to run code across different vendors, listen and learn how digital virtualization might play a key role.

Let’s look to 2026 and recap a pivotal 2025 with Paul Terry, CEO of Photonic. Explore why the industry has officially moved past the era of noisy qubits into the race for fault-tolerant, "gold-standard" logical qubits. Paul joins host Konstantinos Karagiannis to break down Photonic’s selection for DARPA’s Quantum Benchmarking Initiative Stage B and explains how their unique distributed architecture — which uses telecom-grade photons to entangle qubits across networks — allows them to bypass the scaling limitations of monolithic chips. He also details the game-changing shift to LDPC error correction codes, which is drastically reducing the physical resources needed to achieve utility-scale quantum computing. 
  
Paul offers a series of provocative predictions for the coming year, ranging from G7 governments "leaning in" heavily on funding to the emergence of AI as the primary interface for programming quantum machines. He outlines an ambitious roadmap to have 40,000 logical qubits in service by 2030, unlocking massive potential in chemistry and finance, while also addressing the looming reality of the quantum threat to encryption. Tune in to hear why the network is becoming the computer and why the coming year will be defined by business cases rather than hardware metrics.

Traffic congestion isn't just a daily annoyance; it’s a multi-billion dollar drain on the global economy. In this episode, we explore a concrete, real-world application of quantum computing that aims to solve this problem today. Tal David, Co-founder and CEO of Quantum Art, joins host Konstantinos Karagiannis to discuss the company’s major new partnership with Ayalon Highways in Israel. Tal breaks down how they are moving beyond theoretical simulations to use quantum algorithms for synchronizing traffic lights and managing flow in metropolitan areas, potentially reducing commute times and optimizing city planning in ways classical computers simply can't handle. 
  
Beyond the use case, Tal takes us under the hood of Quantum Art’s unique trapped-ion architecture. Unlike competitors that rely on physically shuttling ions, Quantum Art utilizes optical tweezers and massive multi-qubit gates to perform operations on dozens of qubits at once, drastically improving speed and fidelity. We also dive into their aggressive roadmap, which includes a 50-qubit system launching soon, a 1,000-qubit "Perspective" system targeted for 2027, and how they are leveraging NVIDIA technology to power the hybrid future of quantum-classical processing.

We cover post-quantum cryptography (PQC) regularly on this show, focusing on the new math-based ciphers that will secure the Internet as quantum computing becomes more powerful. But what about physics-based encryption or quantum key distribution (QKD)? Is that still a thing? We examine how exploiting the laws of quantum physics can securely exchange encryption keys over a fiber and explore the benefits of the newer continuous-variable QKD. CVQKD leverages off-the-shelf telecom components for affordability, integrates with existing data networks, achieves higher key-generation rates, and reaches distances of up to 100 kilometers without requiring dark fibers. Real-world demos include securely linking hospitals in Madrid for remote consultations via Telefonica's network, and there could be a future where QKD devices are integrated into our home routers, democratizing quantum security. Join host Konstantinos Karagiannis for a wide-ranging chat with Vanesa Diaz from LuxQuanta.

The word “foundry” might make you think of large machines pouring metal into molds, but Argonne National Labs has a Quantum Foundry that implants individual atoms, like silicon, into materials such as diamond. The resulting spin qubits are optically active and can use photons to communicate. We can expect spin qubits to help interconnect systems, which could help us achieve distributed quantum computing, but they also could be used for everything from room-temperature biological sensors to durable, space-based dark matter detectors. Join host Konstantinos Karagiannis for a cosmic chat with Benjamin Pingault from Argonne National Laboratory.
