Multi-Boundary Many-Body Quantum Teleportation
Tal Schwartzman, Antonio F. Rotundo, Raz Monsonego +1
Unlike standard quantum teleportation, many-body teleportation uses scrambling to transmit quantum information. In this protocol, initially localized information spreads over many…
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…
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…
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…
The Complexity of Being Entangled
Stefano Baiguera, Shira Chapman, Giuseppe Policastro +1
Nielsen's approach to quantum state complexity relates the minimal number of quantum gates required to prepare a state to the length of geodesics computed with a certain norm on th…
