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…
