An experimental apparatus for measuring the Casimir effect at large distances

P Antonini, G Bimonte, G Bressi +4

An experimental set-up for the measurement of the Casimir effect at separations larger than a few microns is presented. The apparatus is based on a mechanical resonator and uses a…

Optimal covariant quantum networks

G. Chiribella, G. M. D'Ariano, P. Perinotti

A sequential network of quantum operations is efficiently described by its quantum comb, a non-negative operator with suitable normalization constraints. Here we analyze the case o…

The Quantum No-Stretching: A geometrical interpretation of the no-cloning theorem

Giacomo Mauro D'Ariano, Paolo Perinotti

We consider the ideal situation in which a space rotation is transferred from a quantum spin j to a quantum spin l different from j. Quantum-information theoretical considerations…

Spinor Dynamics of Quantum Accelerator Modes near Higher Order Resonances

L. Rebuzzini, I. Guarneri, R. Artuso

Quantum Accelerator Modes were discovered in experiments with Kicked Cold Atoms in the presence of gravity. They were shown to be tightly related to resonances of the Quantum Kicke…

Realization schemes for quantum instruments in finite dimensions

Giulio Chiribella, Giacomo Mauro D'Ariano, Paolo Perinotti

We present a general dilation scheme for quantum instruments with continuous outcome space in finite dimensions, in terms of an indirect POVM measurement performed on a finite dime…

Robust strategies for lossy quantum interferometry

Lorenzo Maccone, Giovanni De Cillis

We give a simple multiround strategy that permits to beat the shot noise limit when performing interferometric measurements even in the presence of loss. In terms of the average ph…

Adaptive Bayesian and frequentist data processing for quantum tomography

G. M. D'Ariano, D. F. Magnani, P. Perinotti

The outcome statistics of an informationally complete quantum measurement for a system in a given state can be used to evaluate the ensemble expectation of any linear operator in t…

Architectures for a quantum random access memory

Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone

A random access memory, or RAM, is a device that, when interrogated, returns the content of a memory location in a memory array. A quantum RAM, or qRAM, allows one to access superp…

Optimal quantum tomography for states, measurements, and transformations

A. Bisio, G. Chiribella, G. M. D'Ariano +2

We present the first complete optimization of quantum tomography, for states, POVMs, and various classes of transformations, for arbitrary prior ensemble and arbitrary representati…

Quantum Accelerator Modes near Higher-Order Resonances

Italo Guarneri, Laura Rebuzzini

Quantum Accelerator Modes have been experimentally observed, and theoretically explained, in the dynamics of kicked cold atoms in the presence of gravity, when the kicking period i…

Memory effects in quantum channel discrimination

Giulio Chiribella, Giacomo M. D'Ariano, Paolo Perinotti

We consider quantum-memory assisted protocols for discriminating quantum channels. We show that for optimal discrimination of memory channels, memory assisted protocols are needed.…

Transforming quantum operations: quantum supermaps

G. Chiribella, G. M. D'Ariano, P. Perinotti

We introduce the concept of quantum supermap, describing the most general transformation that maps an input quantum operation into an output quantum operation. Since quantum operat…

Optimal cloning of unitary transformations

G. Chiribella, G. M. D'Ariano, P. Perinotti

After proving a general no-cloning theorem for black boxes, we derive the optimal universal cloning of unitary transformations, from one to two copies. The optimal cloner is realiz…

Qubit channels with small correlations

Filippo Caruso, Vittorio Giovannetti, Chiara Macchiavello +1

We introduce a class of quantum channels with correlations acting on pairs of qubits, where the correlation takes the form of a shift operator onto a maximally entangled state. We…
