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,…
