Imaginary time evolution and ground state preparation using unitary multi-copy protocols
Tal Schwartzman, Torsten V. Zache, Hannes Pichler +1
Efficient low-energy state preparation is a key objective in quantum computation and quantum simulation. Quantum imaginary-time evolution replaces real-time dynamics with imaginary…

The complexity of entanglement embezzlement
Tal Schwartzman
Embezzlement of entanglement is the counterintuitive process in which entanglement is extracted from a resource system using local unitary operations, with almost no detectable cha…

Entanglement spectra from holography
Stefano Baiguera, Shira Chapman, Christian Northe +2
The entanglement spectrum of a bipartite quantum system is given by the distribution of eigenvalues of the modular Hamiltonian. In this work, we compute the entanglement spectrum i…
