Results of PRG347
As a result of joint work on the PRG347 project “Spectroscopy of entangled states of clusters of rare-earth impurity ions for quantum computing”, the Laboratories of Laser Spectroscopy and Solid State Theory of the Institute of Physics of the University of Tartu proposed a design and a way to create a new type of optical quantum computers - ultrafast quantum computers with qubits (quantum bits) of optical frequencies without using a magnetic field. The working element of such computers can be microcrystals synthesized on the basis of mixed optical fluoride crystal matrices doped with praseodymium, neodimium, erbium, and thulium ions. Such crystal matrices are commonly used as active elements for lasers. Methods for controlling quantum logic gates (CNOT) and some others using laser pulses are proposed, allowing quantum computing at high speed. Due to the ultra-fast working cycle, the developing quantum computers will make it possible to overcome the main difficulties arising in the creation of quantum computers associated with the short coherence time of qubits. The experimental work is in progress.
