Spatial overhead reduction for 2D hypergraph product codes
Aarav Pabla, Yu-Xin Wang, Yifan Hong
The hypergraph product creates a quantum stabilizer code from two input classical linear codes; a paradigmatic example being the surface code as a hypergraph product of two classic…
Quantum metrology enhanced by effective time reversal
Yu-Xin Wang, Flavio Salvati, David R. M. Arvidsson-Shukur +3
Quantum metrology involves the application of quantum resources to enhance measurements. Several communities have developed quantum-metrology strategies that leverage effective tim…
An Approach to Probing Particles and Quasi-particles in the Condensed Bose-Hubbard Model
Huy Nguyen, Yu-Xin Wang, Jacob M. Taylor
Measurement plays a crucial role in a quantum system beyond just learning about the system state: it changes the post-measurement state and hence influences the subsequent time evo…
Proposals for experimentally realizing quantum-autonomous gates
José Antonio Marín Guzmán, Yu-Xin Wang, Tom Manovitz +4
Autonomous quantum machines (AQMs) execute tasks without requiring time-dependent external control. Motivations for AQMs include the restrictions imposed by classical control on qu…
Superconducting-antiqubit simulation enables optimal phase estimation via unitary inversion
Xingrui Song, Surihan Sean Borjigin, Flavio Salvati +4
A positron is equivalent to an electron traveling backward through time. Casting transmon superconducting qubits as akin to electrons, we simulate a positron with a transmon subjec…
Robust analog quantum simulators by quantum error-detecting codes
Yingkang Cao, Suying Liu, Haowei Deng +3
Achieving noise resilience is an outstanding challenge in Hamiltonian-based quantum computation. To this end, energy-gap protection provides a promising approach, where the desired…
