Faster Probabilistic Error Cancellation
Yi-Hsiang Chen
Probabilistic error cancellation (PEC) is a leading quantum error mitigation method that provides an unbiased estimate, although it is known to have a large sampling overhead. In t…
Quantum state driving: measurements versus pulses
Yi-Hsiang Chen
The quantum Zeno effect is well-known for fixing a system to an eigenstate by frequent measurements. It is also known that applying frequent unitary pulses induces a Zeno subspace…
Quantum algorithm for time-dependent Hamiltonian simulation by permutation expansion
Yi-Hsiang Chen, Amir Kalev, Itay Hen
We present a quantum algorithm for the dynamical simulation of time-dependent Hamiltonians. Our method involves expanding the interaction-picture Hamiltonian as a sum of generalize…
Continuous quantum error detection and suppression with pairwise local interactions
Yi-Hsiang Chen, Todd A. Brun
Performing measurements for high-weight operators has been a practical problem in quantum computation, especially for quantum codes in the stabilizer formalism. The conventional pr…
Qubit POVMs by destructive weak measurements
Yi-Hsiang Chen, Todd A. Brun
Many quantum measurements, such as photodetection, can be destructive. In photodetection, when the detector clicks a photon has been absorbed and destroyed. Yet the lack of a click…
Decomposing qubit positive-operator valued measurements into continuous destructive weak measurements
Yi-Hsiang Chen, Todd A. Brun
It has been shown that any generalized measurement can be decomposed into a sequence of weak measurements corresponding to a stochastic process. However, the weak measurements may…
