Dynamical control of quantum state transfer within hybrid open systems
Dynamical control quantum state transfer hybrid open systems
2010/11/8
We analyze quantum state-transfer optimization within hybrid open systems, from a "noisy" (write-in) qubit to its "quiet" counterpart (storage qubit). Intriguing interplay is revealed between our abil...
Adiabatic quantum state transfer in non-uniform triple-quantum-dot system
Adiabatic quantum state transfer non-uniform triple-quantum-dot system
2010/11/5
We introduce an adiabatic quantum state transfer scheme in a non-uniform coupled triple-quantum-dot system. By adiabatically varying the external gate voltage applied on the sender and receiver, the e...

Bang-Bang Control Design Quantum State Transfer Hyperspherical Coordinates Optimal Time-energy Control
2010/10/21
We present a constructive control scheme for solving quantum state engineering problems based on a parametrization of the state vector in terms of complex hyperspherical coordinates. Unlike many contr...
