Iliauni Professor Giorgi Veshapidze will conduct a public seminar titled "Quantum Computing with Cold Atoms in 2D Optical Tweezer Array" at 18:00 on May 24 in the T302 Room of Ilia State University.

Quantum computing of ultracold atomic gases trapped in 2D Optical Tweezer Arrays (with a period of multiple microns) is an emerging, rapidly developing, and promising direction of quantum computer realization.

In this realization of the quantum computer

• the nuclear spin of an atom trapped in optical tweezers acts as a qubit;
• the qubit is addressed by modulating the intensity of the optical tweezers (inducing the shift of nuclear electric resonance)
• qubits are manipulated by resonant excitation of valence electrons in the outermost shell of the atom (using an optical band laser);
• adjacent qubits entangle (which is necessary to build a universal set of elementary quantum gates/operations) by exciting them to a Rydberg level (also with an optical band laser);
• qubits are read out using a digital camera and a microscope.

This quantum computing scheme provides specialists with significant advantages compared to other alternatives.

The speaker will present an overview of elementary theoretical fundamentals, experimental methods, and the latest achievements.
