Adaptive estimation of qubits by symmetry measurements
Christof J. Happ, Matthias Freyberger
We analyze quantum state estimation for finite samples based on symmetry information. The used measurement concept compares an unknown qubit to a reference state. We describe expli…
Upper bounds on fault tolerance thresholds of noisy Clifford-based quantum computers
M. B. Plenio, S. Virmani
We consider the possibility of adding noise to a quantum circuit to make it efficiently simulatable classically. In previous works this approach has been used to derive upper bound…
Critical exponents of one-dimensional quantum critical models by means of MERA tensor network
S. Montangero, M. Rizzi, V. Giovannetti +1
An algorithm for optimizing the MERA tensor network in an infinite system is presented. Using this technique we compute the critical exponents of Ising and XXZ model.
High-fidelity fast quantum transport with imperfect controls
Michael Murphy, Liang Jiang, Navin Khaneja +1
Effective transport of quantum information is an essential element of quantum computation. We consider the problem of transporting a quantum state by using a moving potential well,…
System-bath entanglement in nanothermodynamics
Stefanie Hilt, Eric Lutz
We consider a quantum harmonic oscillator linearly coupled to a bath of harmonic oscillators and evaluate the degree of entanglement between system and bath using the negativity as…
Employing trapped cold ions to verify the quantum Jarzynski equality
Gerhard Huber, Ferdinand Schmidt-Kaler, Sebastian Deffner +1
We propose a scheme to investigate the nonequilibrium work distribution of a quantum particle under well controlled transformations of the external potential, exploiting the versat…
