Efficient and robust adiabatic universal quantum computation using STIRAP on a qubit chain
Toshio Ohshima
It is shown that efficient and robust universal quantum computation is possible using the stimulated Raman adiabatic passage with a qubit chain as a pointer register.
Robust state transfer and rotation through a spin chain via dark passage
Toshio Ohshima, Artur Ekert, Daniel K. L. Oi +2
Quantum state transfer through a spin chain via adiabatic dark passage is proposed. This technique is robust against control field fluctuations and unwanted environmental coupling…
Detecting entanglement with a thermometer
Janet Anders, Dagomir Kaszlikowski, Christian Lunkes +2
We present a general argument showing that the temperature as well as other thermodynamical state variables can qualify as entanglement witnesses for spatial entanglement. This hol…
Surface Acoustic Wave Single-Electron Interferometry
Roberta Rodriquez, Daniel K. L. Oi, Crispin H. W. Barnes +3
We propose an experiment to observe interference of a single electron as it is transported along two parallel quasi-one-dimensional channels trapped in a single minimum of a travel…
Molecular states observed in a single pair of strongly coupled self-assembled InAs quantum dots
T. Ota, M. Stopa, M. Rontani +8
Molecular states in a SINGLE PAIR of strongly coupled self-assembled InAs quantum dots are investigated using a sub-micron sized single electron transistor containing just a few pa…
All Optical Cellular Quantum Computer having Ancilla Bits for Operations in Each Cell
Toshio Ohshima
A quantum cellular network with a qubit and ancilla bits in each cell is proposed. The whole circuit works only with the help of external optical pulse sequences. In the operation,…
