Variational Monte Carlo simulation with tensor networks of a pure gauge theory in (2+1)d
Patrick Emonts, Mari Carmen Bañuls, J. Ignacio Cirac +1
Variational minimization of tensor network states enables the exploration of low energy states of lattice gauge theories. However, the exact numerical evaluation of high-dimensiona…
Geometry of variational methods: dynamics of closed quantum systems
Lucas Hackl, Tommaso Guaita, Tao Shi +3
We present a systematic geometric framework to study closed quantum systems based on suitably chosen variational families. For the purpose of (A) real time evolution, (B) excitatio…
Efficient quantum computation in a network with probabilistic gates and logical encoding
Johannes Borregaard, Anders S. Sørensen, Ignacio Cirac +1
A new approach to efficient quantum computation with probabilistic gates is proposed and analyzed in both a local and non-local setting. It combines heralded gates previously studi…
Ion crystal transducer for strong coupling between single ions and single photons
L. Lamata, D. R. Leibrandt, I. L. Chuang +4
A new approach for realization of a quantum interface between single photons and single ions in an ion crystal is proposed and analyzed. In our approach the coupling between a sing…
How long can a quantum memory withstand depolarizing noise?
Fernando Pastawski, Alastair Kay, Norbert Schuch +1
We investigate the possibilities and limitations of passive Hamiltonian protection of a quantum memory against depolarizing noise. Without protection, the lifetime of a single qubi…
Operational criterion and constructive checks for the separability of low rank density matrices
Pawel Horodecki, Maciej Lewenstein, Guifré Vidal +1
We consider low rank density operators supported on a Hilbert space for arbitrary and () and with a positive partial transpose (PPT) $\varrho…
