How thermal is a filtered state?
Yilun Yang, J. Ignacio Cirac, Mari Carmen Bañuls
Quantum many-body states with sufficiently low energy variance can serve as approximations to thermal states, and they may be prepared by energy filtering simple pure states. In th…
Dissipative phase decision without ground-state preparation
Hao-En Li, Yilun Yang, Lin Lin
We propose a dynamical approach to identifying ground-state quantum phases through short-time dissipative cooling. Rather than determining the phase by preparing highly accurate ap…
Quantum Filtering and Analysis of Multiplicities in Eigenvalue Spectra
Zhiyan Ding, Lin Lin, Yilun Yang +1
Fine-grained spectral properties of quantum Hamiltonians, including both eigenvalues and their multiplicities, provide useful information for characterizing many-body quantum syste…
Phase-Sensitive Quantum Measurement without Controlled Operations
Yilun Yang, Arthur Christianen, Mari Carmen Bañuls +2
Many quantum algorithms rely on the measurement of complex quantum amplitudes. Standard approaches to obtain the phase information, such as the Hadamard test, give rise to large ov…
Simulating prethermalization using near-term quantum computers
Yilun Yang, Arthur Christianen, Sandra Coll-Vinent +5
Quantum simulation is one of the most promising scientific applications of quantum computers. Due to decoherence and noise in current devices, it is however challenging to perform…
Classical algorithms for many-body quantum systems at finite energies
Yilun Yang, J. Ignacio Cirac, Mari Carmen Bañuls
We investigate quantum inspired algorithms to compute physical observables of quantum many-body systems at finite energies. They are based on the quantum algorithms proposed in [Lu…
Nuclear chart in covariant density functional theory with dynamical correlations: From Oxygen to Tin
Yi-Long Yang, Ya-Kun Wang
Nuclear masses of even-even nuclei with the proton number (O to Sn isotopes) from proton drip line to neutron drip line are investigated using the triaxial relativ…
Probing thermalization through spectral analysis with matrix product operators
Yilun Yang, Sofyan Iblisdir, J. Ignacio Cirac +1
We combine matrix product operator techniques with Chebyshev polynomial expansions and present a method that is able to explore spectral properties of quantum many-body Hamiltonian…
