Measurement-induced Clock in a Lattice Ring of Non-interacting Electrons
David S. Schlegel, Stefan Kehrein
We examine the emergence of periodicity in a non-interacting steady-state quantum system without external drive inspired by quantum time crystals' spontaneous time-translation symm…
Coherent-State Ladder Time-Dependent Variational Principle for Open Quantum Systems
David S. Schlegel, Fabrizio Minganti, Vincenzo Savona
We present a new paradigm for the dynamical simulation of interacting many-boson open quantum systems. The method relies on a variational ansatz for the -boson density matrix, i…
Quantum error correction using squeezed Schrödinger cat states
David S. Schlegel, Fabrizio Minganti, Vincenzo Savona
Bosonic quantum codes redundantly encode quantum information in the states of a quantum harmonic oscillator, making it possible to detect and correct errors. Schrödinger cat codes…
