$mathbb{Z}_4$ transitions in quantum loop models on a zig-zag ladder

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Bowy M. La Rivière, Natalia Chepiga, , , | Summary: We study the nature of quantum phase transitions out of $mathbb{Z}_4$ ordered phases in quantum loop models on a zig-zag ladder. We report very rich critical behaviour that includes a pair of Ising transitions, a multi-critical Ashkin-Teller […]

ML-Powered FPGA-based Real-Time Quantum State Discrimination Enabling Mid-circuit Measurements

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Neel R. Vora, Yilun Xu, Akel Hashim, Neelay Fruitwala, Ho Nam Nguyen | Summary: Similar to reading the transistor state in classical computers, identifying the quantum bit (qubit) state is a fundamental operation to translate quantum information. However, identifying quantum state has been the slowest and most […]

Constant search time algorithm via topological quantum walks

Kavli Affiliate: Eliska Greplova | First 5 Authors: D. O. Oriekhov, Guliuxin Jin, Eliska Greplova, , | Summary: It is well-known that quantum algorithms such as Grover’s can provide a quadradic speed-up for unstructured search problems. By adding topological structure to a search problem, we show that it is possible to achieve a constant search-time […]
