Spin-incoherent Mott-Thouless pumps
Ajesh Kumar, Urban F. P. Seifert, Erez Berg +1
A Thouless pump describes a system in which a quantized amount of charge is transported by one lattice spacing per cycle when the parameters of a Hamiltonian are varied slowly and…
Vari-Cool: a non-unitary quantum variational protocol for simulated cooling
Jeffrey Z. Song, Gilad Kishony, Erez Berg +1
We introduce a variational approach for preparing low energy states of arbitrary target Hamiltonians. The protocol is defined in terms of a repeated cycle consisting of p layers of…
Increasing the distance of topological codes with time vortex defects
Gilad Kishony, Erez Berg
We propose modifying topological quantum error correcting codes by incorporating space-time defects, termed ``time vortices,'' to reduce the number of physical qubits required to a…
Topological excitations at time vortices in periodically driven systems
Gilad Kishony, Ori Grossman, Netanel Lindner +2
We consider two-dimensional periodically driven systems of fermions with particle-hole symmetry. Such systems support non-trivial topological phases, including ones that cannot be…
Efficiently preparing chiral states via fermionic cooling on bosonic quantum hardware
Gilad Kishony, Mark S. Rudner, Erez Berg
Simulating many-body systems is one of the most promising applications of near-term quantum computers. An important open question is how to efficiently prepare the ground states of…
Gauged cooling of topological excitations and emergent fermions on quantum simulators
Gilad Kishony, Mark S. Rudner, Achim Rosch +1
Simulated cooling is a robust method for preparing low-energy states of many-body Hamiltonians on near-term quantum simulators. In such schemes, a subset of the simulator's spins (…
