Large Gauge Transformations and the Light-Front Vacuum Structure
L. Martinovic
A residual gauge symmetry, exhibited by light-front gauge theories quantized in a finite volume, is analyzed at the quantum level. Unitary operators, which implement the symmetry,…
Slow Forcing in the Projective Dynamics Method
M. A. Novotny, M. Kolesik, P. A. Rikvold
We provide a proof that when there is no forcing the recently introduced projective dynamics Monte Carlo algorithm gives the exact lifetime of the metastable state, within statisti…
Center Projection With and Without Gauge Fixing
M. Faber, J. Greensite, S. Olejnik
We consider projections of SU(2) lattice link variables onto Z(2) center and U(1) subgroups, with and without gauge-fixing. It is shown that in the absence of gauge-fixing, and up…
Asymptotic Scaling, Casimir Scaling, and Center Vortices
M. Faber, J. Greensite, S. Olejnik
We report on two recent developments in the center vortex theory of confinement: (i) the asymptotic scaling of the vortex density, as measured in Monte Carlo simulations; and (ii)…
Optimal Quantum Clocks
V. Buzek, R. Derka, S. Massar
A quantum clock must satisfy two basic constraints. The first is a bound on the time resolution of the clock given by the difference between its maximum and minimum energy eigenval…
Quantum synthesis of 3D vibrational states of trapped ions
B. Hladky, G. Drobny, V. Buzek
A universal algorithm for a deterministic preparation of arbitrary three--mode bosonic states is introduced. In particular, we consider preparation of entangled quantum states of a…
Reconstruction of Liouvillian Superoperators
Vladimir Buzek
We show how to determine (reconstruct) a master equation governing the time evolution of an open quantum system. We present a general algorithm for the reconstruction of the corres…
Quantum secret sharing
M. Hillery, V. Buzek, A. Berthiaume
Secret sharing is a procedure for splitting a message into several parts so that no subset of parts is sufficient to read the message, but the entire set is. We show how this proce…
Quantum State Reconstruction From Incomplete Data
V. Buzek, G. Drobny, R. Derka +2
Knowing and guessing, these are two essential epistemological pillars in the theory of quantum-mechanical measurement. As formulated quantum mechanics is a statistical theory. In g…
Detection of Center Vortices in the Lattice Yang-Mills Vacuum
L. Del Debbio, M. Faber, J. Giedt +2
We discuss the implementation of the ``direct'' maximal center gauge (a gauge which maximizes the lattice average of the squared-modulus of the trace of link variables), and its us…
Universal optimal cloning of qubits and quantum registers
Vladimir Buzek, Mark Hillery
We review our recent work on the universal (i.e. input state independent) optimal quantum copying (cloning) of qubits. We present unitary transformations which describe the optimal…
Quantum-state synthesis of multi-mode bosonic fields: Preparation of arbitrary states of 2-D vibrational motion of trapped ions
G. Drobny, B. Hladky, V. Buzek
We present a universal algorithm for an efficient deterministic preparation of an arbitrary two--mode bosonic state. In particular, we discuss in detail preparation of entangled st…
