Parametric amplification by coupled flux qubits
M. Rehak, P. Neilinger, M. Grajcar +4
We report the parametric amplification of a microwave signal in a Kerr medium formed from superconducting qubits. Two mutually coupled flux qubits, embedded in the current antinode…
Maximally incompatible quantum observables
Teiko Heinosaari, Jussi Schultz, Alessandro Toigo +1
The existence of maximally incompatible quantum observables in the sense of a minimal joint measurability region is investigated. Employing the universal quantum cloning device it…
The Local Hamiltonian problem on a line with eight states is QMA-complete
Sean Hallgren, Daniel Nagaj, Sandeep Narayanaswami
The Local Hamiltonian problem is the problem of estimating the least eigenvalue of a local Hamiltonian, and is complete for the class QMA. The 1D problem on a chain of qubits has h…
Electric control of tunneling energy in graphene double dots
Martin Raith, Christian Ertler, Peter Stano +2
We theoretically investigate the spectrum of a single electron double quantum dot, defined by top gates in a graphene with a substrate induced gap. We examine the effects of electr…
Measuring the ground-state wave functional of SU(2) Yang-Mills theory in 3+1 dimensions: Abelian plane waves
Jeff Greensite, Stefan Olejnik
A method of measuring relative probabilities of various gauge-field configurations in the Yang-Mills vacuum was proposed long ago [Phys. Lett. B 223 (1989) 207]. We applied this me…
Numerical study of the Yang-Mills vacuum wavefunctional in D=3+1 dimensions
Jeff Greensite, Stefan Olejnik
Ratios of the true Yang-Mills vacuum wavefunctional, evaluated on any two field configurations out of a finite set of configurations, can be obtained from lattice Monte Carlo simul…
Status of the Exclusive MSSM Higgs production at LHC after the Run I
Marek Tasevsky
We investigate the prospects for Central Exclusive Diffractive (CED) production of MSSM Higgs bosons at the LHC using forward proton detectors (FPD) proposed to be installed 220 m…
Dissociation and annihilation of multipartite entanglement structure in dissipative quantum dynamics
Sergey N. Filippov, Alexey A. Melnikov, Mario Ziman
We study the dynamics of the entanglement structure of a multipartite system experiencing a dissipative evolution. We characterize the processes leading to a particular form of out…
The SAT-UNSAT transition in the adversarial SAT problem
Marco Bardoscia, Daniel Nagaj, Antonello Scardicchio
Adversarial SAT (AdSAT) is a generalization of the satisfiability (SAT) problem in which two players try to make a boolean formula true (resp. false) by controlling their respectiv…
Comment on "Quantum Szilard Engine"
Martin Plesch, Oscar Dahlsten, John Goold +1
In a recently published letter [S. W. Kim, T. Sagawa, S. DeLiberato, and M. Ueda, PRL 106, 070401 (2011)] the influence of particle statistics on extractable work in the Szilard en…
Spin Hot Spots in Single-Electron GaAs-based Quantum Dots
Martin Raith, Thomas Pangerl, Peter Stano +1
Spin relaxation of a single electron in a weakly coupled double quantum dot is calculated numerically. The phonon assisted spin flip is allowed by the presence of the linear and cu…
Optimal processing of reversible quantum channels
Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti +1
We consider the general problem of the optimal transformation of N uses of (possibly different) unitary channels to a single use of another unitary channel in any finite dimension.…
Topological Superconductivity and Majorana Fermions in RKKY Systems
Jelena Klinovaja, Peter Stano, Ali Yazdani +1
We consider quasi one-dimensional RKKY systems in proximity to an s-wave superconductor. We show that a -peak in the spin susceptibility of the superconductor in the one-dime…
Fault-ignorant Quantum Search
Peter Vrana, David Reeb, Daniel Reitzner +1
We investigate the problem of quantum searching on a noisy quantum computer. Taking a 'fault-ignorant' approach, we analyze quantum algorithms that solve the task for various diffe…
Bipartite entanglement-annihilating maps: necessary and sufficient conditions
S. N. Filippov, M. Ziman
We fully characterize bipartite entanglement-annihilating (EA) channels that destroy entanglement of any state shared by subsystems and, thus, should be avoided in any entanglement…
Circuit QED with Hole-Spin Qubits in Ge/Si Nanowire Quantum Dots
Christoph Kloeffel, Mircea Trif, Peter Stano +1
We propose a setup for universal and electrically controlled quantum information processing with hole spins in Ge/Si core/shell nanowire quantum dots (NW QDs). Single-qubit gates c…
Rigidity of the conductance of anchored dithioazobenzene opto-mechanical switch
M. Zemanová Diešková, I. Štich, P. Bokes
Reversible opto-mechanical molecular switch based on a single azobenzene molecule suspended via thiolate links between realistic models of gold tips is investigated. Using a combin…
Can Eta mesons have a magnetic moment ?
Peter Filip
The response of pseudoscalar and vector mesons to strong magnetic fields is studied within a simple constituent quark model using analogy with bound states of Positronium. Magnetic…
Device-independent randomness amplification with a single device
Martin Plesch, Matej Pivoluska
Expansion and amplification of weak randomness with untrusted quantum devices has recently become a very fruitful topic of research. Here we contribute with a procedure for amplify…
Counter-ions at single charged wall: Sum rules
Ladislav Samaj
For inhomogeneous classical Coulomb fluids in thermal equilibrium, like the jellium or the two-component Coulomb gas, there exists a variety of exact sum rules which relate the par…
Thermodynamics of two-component log-gases with alternating charges
Ladislav Samaj
We consider a one-dimensional gas of positive and negative unit charges interacting via a logarithmic potential, which is in thermal equilibrium at the (dimensionless) inverse temp…
