Quantum Information Processing Laboratory Stations

Quantum information processing (QIP) laboratory stations exist, or are being established, in several Technion laboratories. In some of these laboratories, active cooperation is exercised between the Computer Science Department and the department which hosts the laboratory. In others, various cooperation possibilities exists. The cooperation takes form as equipment sharing, joint projects, employment of researchers and post-doctorants, supervision of graduate students, and suggestion of projects for undergraduate students.

The goals of a QIP laboratory station (from the point of view of the Computer Science Department) are:

• Implementing hardware that is required for quantum computation or quantum communication/encryption.
• Solve quantum computation problems such as scalability and universality, or and related to security and efficiency of communication.

1. The Station of Optical Quantum Computation, Communication, and Cryptography

This QIP station is managed by Dr. Tal Mor (Computer Science) and Prof. Meir Orenstein (Electrical Engineering). The station is located in the Microphotonics Laboratory in the Electrical Engineering Department. Resources for purchasing equipment (especially equipment that handles single photons) and financing post-doctoral fellowships are being raised. Research is conducted in the following subjects:

• Quantum computation with linear optics
• Quantum encryption by single photons
• Qubits implemented by angular momentum of coherent light.

2. The Station of Liquid NMR Quantum Computation and Algorithmic Cooling of Spins

The experimental apparatus for quantum computation with liquid NMR is under the joint supervision of Dr. Tal Mor (Computer Science) and Prof. Haggai Gilboa (Chemistry). The station is located in the NMR Laboratory of the Faculty of Chemistry, where the experimentation takes place on the "Bruker Avance" NMR machines.

The activity includes:

• Quantum Computation qith Liquid NMR.
• Algorithmic Cooling of spins.

3. Additional Stations

Besides those stations, there exists the possibility of cooperation with Dr. Eyal Buks's (Electrical Engineering) in planning a solid-state qubits station, and Dr. Zohar Amitay's (Chemistry) in planning a station of quantum computing via coherent control of molecular systems.
