چکیده
We investigate the most general mechanisms that lead to perfect synchronization of quantum states all subsystems an open system starting from arbitrary initial state. provide a necessary and sufficient condition for such ``quantum-state synchronization,'' prove tight lower bounds on dimension ancilla's Hilbert space in two main classes quantum-state synchronizers, give analytical solution their construction. The functioning found synchronizer qubits is demonstrated experimentally IBM computer we show remaining asynchronicity sensitive measure computer's imperfection.

Perfect state transfer in quantum spin networks.
We propose a class of qubit networks that admit the perfect state transfer of any quantum state in a fixed period of time. Unlike many other schemes for quantum computation and communication, these networks do not require qubit couplings to be switched on and off. When restricted to N-qubit spin networks of identical qubit couplings, we show that 2log3N is the maximal perfect communication dist...
متن کاملPerfect Coding for Dephased Quantum State Transfer
Near-future realisations of quantum technologies, from simple state-generation tasks [1–3] to analogue quantum simulation [4], will be small scale and will rely on intrinsic properties of the system to facilitate as much of their functionality as possible, rather than trying to impose error-prone operations to strong-arm the system into performing tasks. For example, existing quantum simulators...
متن کاملPerfect quantum state transfer with randomly coupled quantum chains
We suggest a scheme that allows arbitrarily perfect state transfer even in the presence of random fluctuations in the couplings of a quantum chain. The scheme performs well for both spatially correlated and uncorrelated fluctuations if they are relatively weak (say 5%). Furthermore, we show that given a quite arbitrary pair of quantum chains, one can check whether it is capable of perfect trans...
متن کاملPerfect quantum state transfer with spinor bosons on weighted graphs.
A duality between the properties of many spinor bosons on a regular lattice and those of a single particle on a weighted graph reveals that a quantum particle can traverse an infinite hierarchy of networks with perfect probability in polynomial time, even as the number of nodes increases exponentially. The one-dimensional "quantum wire" and the hypercube are special cases in this construction, ...
متن کاملEfficient and perfect state transfer in quantum chains
We present a communication protocol for chains of permanently coupled qubits which achieves perfect quantum state transfer and which is efficient with respect to the number chains employed in the scheme. The system consists of M uncoupled identical quantum chains. Local control (gates, measurements) is only allowed at the sending/receiving end of the chains. Under a quite general hypothesis on ...
