A novel experimental approach for the detection of the dynamic Casimir effect
C. Braggio, G. Bressi, G. Carugno +6
The Casimir effect is a well-known macroscopic consequence of quantum vacuum fluctuations, but whereas the static effect (Casimir force) has long been observed experimentally, the…
Optimal phase estimation for qubit mixed states
Giacomo Mauro D'Ariano, Chiara Macchiavello, Paolo Perinotti
We address the problem of optimal estimation of the relative phase for two-dimensional quantum systems in mixed states. In particular, we derive the optimal measurement procedures…
Efficient universal programmable quantum measurements
Giacomo Mauro D'Ariano, Paolo Perinotti
A universal programmable detector is a device that can be tuned to perform any desired measurement on a given quantum system, by changing the state of an ancilla. With a finite dim…
Computing Spin Networks
Annalisa Marzuoli, Mario Rasetti
We expand a set of notions recently introduced providing the general setting for a universal representation of the quantum structure on which quantum information stands. The dynami…
Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…
Classical randomness in quantum measurements
Giacomo Mauro D'Ariano, Paoloplacido Lo Presti, Paolo Perinotti
Similarly to quantum states, also quantum measurements can be "mixed", corresponding to a random choice within an ensemble of measuring apparatuses. Such mixing is equivalent to a…
Spin network setting of topological quantum computation
Annalisa Marzuoli, Mario Rasetti
The spin network simulator model represents a bridge between (generalised) circuit schemes for standard quantum computation and approaches based on notions from Topological Quantum…
Economical Phase-Covariant Cloning of Qudits
Francesco Buscemi, Giacomo Mauro D'Ariano, Chiara Macchiavello
We derive the optimal N to M phase-covariant quantum cloning for equatorial states in dimension d with M=kd+N, k integer. The cloning maps are optimal for both global and single-qu…
Efficient use of quantum resources for the transmission of a reference frame
G. Chiribella, G. M. D'Ariano, P. Perinotti +1
We propose a covariant protocol for transmitting reference frames encoded on spins, achieving sensitivity without the need of a pre-established reference frame and wit…
Wave function collapses in a single spin magnetic resonance force microscopy
G. P. Berman, F. Borgonovi, V. I. Tsifrinovich
We study the effects of wave function collapses in the oscillating cantilever driven adiabatic reversals (OSCAR) magnetic resonance force microscopy (MRFM) technique. The quantum d…
Experimental Purification of Single Qubits
M. Ricci, F. De Martini, N. J. Cerf +3
We report the experimental realization of the purification protocol for single qubits sent through a depolarization channel. The qubits are associated with polarization encoded pho…
Path integral in a magnetic field using the Trotter product formula
B. Gaveau, E. Mihokova, M. Roncadelli +1
The derivation of the Feynman path integral based on the Trotter product formula is extended to the case where the system is in a magnetic field.
A Model for Quantum Jumps in Magnetic Resonance Force Microscopy
G. P. Berman, F. Borgonovi, V. I. Tsifrinovich
We propose a simple model which describes the statistical properties of quantum jumps in a single-spin measurement using the oscillating cantilever-driven adiabatic reversals techn…
Survival of quantum effects for observables after decoherence
G. P. Berman, A. R. Bishop, F. Borgonovi +1
When a quantum nonlinear system is linearly coupled to an infinite bath of harmonic oscillators, quantum coherence of the system is lost on a decoherence time-scale . Neverthe…
