Universal energy-space localization and stable quantum phases against time-dependent perturbations
Hongye Yu, Tzu-Chieh Wei
Stability against perturbations is a highly nontrivial property of quantum systems and is often a requirement to define new phases. In most systems where stability can be rigorousl…
The robustness condition for general disordered discrete time crystals, and subspace-thermal DTCs from phase transitions between different n-tuple DTCs
Hongye Yu, Tzu-Chieh Wei
We propose a new Floquet time crystal model that responds in arbitrary multiples of the driving period. Such an -tuple discrete time crystal is theoretically constructed by perm…
Efficient separate quantification of state preparation errors and measurement errors on quantum computers and their mitigation
Hongye Yu, Tzu-Chieh Wei
Current noisy quantum computers have multiple types of errors, which can occur in the state preparation, measurement/readout, and gate operation, as well as intrinsic decoherence a…
Feedback-based Quantum Algorithm Inspired by Counterdiabatic Driving
Rajesh K. Malla, Hiroki Sukeno, Hongye Yu +3
In recent quantum algorithmic developments, a feedback-based approach has shown promise for preparing quantum many-body system ground states and solving combinatorial optimization…
Detecting Multipartite Entanglement Patterns using Single Particle Green's Functions
Rajesh K. Malla, Andreas Weichselbaum, Tzu-Chieh Wei +1
We present a protocol for detecting multipartite entanglement in itinerant many-body electronic systems using single particle Green's functions. To achieve this, we first establish…
