Monday, October 26, 2026 – Wednesday, October 28, 2026 | Quantum Computing Systems and Components | “Quantum computing is entering a new phase: circuits are no longer fixed sequences but can adapt in real time through mid-circuit measurements, conditional logic, and classical feedback loops within the coherence window of the qubits. These adaptive methods are moving from theory into practice and are becoming critical for scalable calibration, quantum error correction, and better algorithmic performance across architectures. AQC26 covers adaptive protocols, mid-circuit measurements, dynamic calibration, quantum error correction, decoding, and hybrid quantum-classical computing, all central both to reaching fault tolerance and to getting useful performance from today’s devices. Each day focuses on a hardware family: neutral atoms and ions on October 26, superconducting qubits on October 27, and spin qubits and beyond on October 28. Keynote speakers include William D. Oliver (MIT), Mark Saffman (UW-Madison and Infleqtion), Gaurav Gyawali (HPE), Morten Kjaergaard (Niels Bohr Institute), Smriti Bajaj (Dell Technologies), Andre Saraiva (Diraq), and Yonatan Cohen (Quantum Machines), with a special online talk by John Martinis, and speakers from Quantinuum, Atom Computing, IonQ, Microsoft, Google Quantum AI, IBM Quantum, Rigetti, NVIDIA, and Fermilab.

Monday, October 26, 2026 | Quantum Algorithms | “Aram Harrow of MIT speaks in the Princeton Quantum Colloquium, the Princeton Quantum Initiative’s lunchtime lecture series on Mondays. His talk, “Trading coherence for randomness in quantum algorithms,” starts from the fact that quantum computers draw their power from coherent interference across many computational paths, which can bring large speedups but is hard to achieve, and asks when costly superpositions can be replaced by cheap randomness. Harrow will describe approaches in both quantum computing and quantum communication, including faster quantum and classical simulations of molecules, quantum optimization over large data sets, and the use of entanglement in distributed quantum computing. The talk is in Bowen Hall, and a light lunch is served in the Bowen Atrium from 11:45 a.m.” | |

Tuesday, October 27, 2026 | Q-Neko webinar: Iterative warm-started QAOA for QUBO problems on noisy quantum hardware | Quantum Algorithms | “An online webinar from Q-Neko (Nippon-Europe Quantum Koraborēshon), a European–Japanese quantum computing and HPC collaboration coordinated by CSC – IT Center for Science in Finland. Ryszard Kukulski and Adam Bílek of IT4Innovations at VSB – Technical University of Ostrava, with Marek Lampart as chair, look at how far a shallow, depth-one QAOA circuit can go on QUBO problems on today’s noisy hardware. They build an iterative loop of short restarts in which the best classically rescored bitstrings seed the next warm start, explain the “warm-start trap,” where the circuit collapses onto its seed, and a noise- directed adaptive warm start that avoids it, and show a small reinforcement learning agent, trained in simulation, that tunes the loop’s settings under a fixed shot budget. The session closes with an outlook toward star-resonator hardware and a Q&A. It suits people with a basic grasp of gate-based quantum computing, and Qiskit familiarity helps. Registration is through a form linked from the event page; the 09:00 CET start is 17:00 in Tokyo.” |

Sunday, August 22, 2027 – Friday, August 27, 2027 | Quantum Computing | “Seeking Quantum Advantage (SEEQA) returns in 2027 after taking 2026 off, following editions in 2024 and 2025. Held at Merton College, Oxford, the workshop and conference gathers about 150 quantum computing experts for invited long and short talks and for debates, which earlier editions held in the Oxford Union debating chamber. Topics include new quantum algorithms and applications, classical simulation and emulation, hardware advances and demonstrations, practical quantum error correction, noise control, fault- tolerant architectures and resource estimation, and the interplay between AI and quantum computing. Simon Benjamin and Bálint Koczor chair the conference, and the program committee includes Aram Harrow, Ryan Babbush, and Elham Kashefi. A poster session with an industry-sponsored prize is planned, and registration will open closer to the event.” | |
