Step Toward Quantum Computers? Scientists Propose A Simple And Economic Qbit Structure

Summary:
Physicists propose new annular structures (quantum rings) to define a qbit, i.e. the unit of information of quantum computers. The proposed system is based on the interaction of laser light with a metallic structure in the form of a ring and which has been written on lithographically. The advantages of the system are its simplicity and its economy, given that its quantic state can be precisely controlled with light and the technique can be integrated into current electronic structures.

The research team from the Physics of Materials group at the University of the Basque Country (UPV/EHU), the UPV/EHU Mixed Centre Physics of Materials group and the European Theoretical Spectroscopy Facility (ETSF), led by Ángel Rubio, has just published a new article in Physical Review Letters journal.

The piece, entitled, Optimal Control of Quantum Rings by Terahertz Laser Pulses 1, proposes new annular structures (quantum rings) to define a qbit, i.e. the unit of information of quantum computers.. The work has been undertaken in collaboration with the Freie-Universität of Berlin and the research team there under university teacher, Eberhard K.U. Gross.

Unlike the binary bit of current computers which only has two possible states – 0 or 1 – the unit of measurement of quantic computers is the qbit which uses a much more complex logic involving multiple states, enabling the much more efficient processing of information. There are many proposed applications for the qbit, some based on quantic points embedded in matrixes, others on magnetic molecules, others on cold atoms, and so on.

The UPV/EHU researchers propose a new system based on the interaction of laser light with a metallic structure in the form of a ring and which has been written on lithographically. The advantages of the system are its simplicity and its economy, given that its quantic state can be precisely controlled with light and the technique can be integrated into current electronic structures. Ángel Rubio and his team are currently working on a combination of a number of these structures so that they may interact and operations can be carried out.
