چکیده
The problem of dephasing channel discrimination is addressed for finite-dimensional systems. In particular, the optimization with respect to input states without energy constraint solved analytically qubit, qutrit and ququart. Additionally, it shown that resorting side entanglement assisted strategy completely useless in this case.

Quantum capacity of dephasing channels with memory
We show that the amount of coherent quantum information that can be reliably transmitted down a dephasing channel with memory is maximized by separable input states. In particular, we model the channel as a Markov chain or a multimode environment of oscillators. While in the first model the maximization is achieved for the maximally mixed input state, in the latter it is convenient to exploit t...
متن کاملLimits to clock synchronization induced by completely dephasing communication channels
There are two main kinds of protocols for achieving clock synchronization. The first is the ‘‘Einstein synchronization protocol’’ @1# in which a signal is sent back and forth between one of the clocks ~say Alice’s clock! and the other clocks. By knowing the signal speed dependence on the intermediate environment, it is possible to synchronize all the clocks with Alice’s. The other main protocol...
متن کاملMinimum error discrimination of Pauli channels
Abstract. We solve the problem of discriminating with minimum error probability two given Pauli channels. We show that, differently from the case of discrimination between unitary transformations, the use of entanglement with an ancillary system can strictly improve the discrimination, and any maximally entangled state allows to achieve the optimal discrimination. We also provide a simple neces...
متن کاملDephasing of entangled qubits
We investigate the influence of nearby two-level systems on the dynamics of a qubit. The intrinsic decoherence is given by a coupling of both the qubit and the two-level systems to a heat bath. Assuming weak interactions between the qubit and the two-level systems we show that the dephasing of the qubit follows a multi-exponential decay. For a flat distribution of energy splittings of the two-l...
متن کاملDiscrimination of compound gratings: Spatial-frequency channels or local features?
Models based on spatial-frequency channels and local features provide alternative explanations for suprathreshold pattern discrimination. We compared psychophysical discrimination data with the predictions of the Wilson and Gelb channel model and three local-feature models. The features were peak-valley local contrast, peak-peak local contrast, and luminance gradients. We measured visual sensit...
