چکیده
We develop the protocol for structural restoring of multi-quantum coherence matrices multi-qubit quantum state transferred from sender to receiver along a spin-1/2 chain. also propose constructing such 0-order matrix that can be perfectly in this process. The is based on specially constructed unitary transformation extended receiver.{This given length parameters chain universally optimal sense ones it applied optimally restore any higher-order matrices.

Topological quantum gate entangler for a multi-qubit state
We establish a relation between topological and quantum entanglement for a multi-qubit state by considering the unitary representations of the Artin braid group. We construct topological operators that can entangle multi-qubit state. In particular we construct operators that create quantum entanglement for multi-qubit states based on the Segre ideal of complex multi-projective space. We also in...
متن کاملDecoherence effects on quantum Fisher information of multi-qubit W states
Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate t...
متن کاملMulti-Qubit Dynamics Quantum Search Algorithm
Following the experimental work [M. W. Johnson, et al. Nature 473, 194 (2011)], we propose a new physical scheme for perfect implementation of quantum search algorithm in presence of the dissipation of qubits. Applying all the required steps for implementing the algorithm, the quantum gates are generated from the suggested model. During a critical portion of quantum annealing, the qubits become...
متن کاملQuantum Feedback Control of a Solid-State Qubit
The principle of feedback control is used in a wide variety of physical and engineering problems. For example, it can be applied in a straightforward way to tune the oscillation phase of a harmonic oscillator in order to achieve a desired synchronization. An intriguing and fundamental question is whether continuous feedback can be used to control quantum systems; for instance, if it is possible...
متن کاملUncollapsing of a quantum state in a superconducting phase qubit
We demonstrate in a superconducting qubit the conditional recovery (“uncollapsing”) of a quantum state after a partial-collapse measurement. A weak measurement extracts information and results in a non-unitary transformation of the qubit state. However, by adding a rotation and a second partial measurement with the same strength, we erase the extracted information, effectively canceling the eff...
