Research on Quantum Bits or Qubits
by Prof. Pratanu Banerjee Bookmark and Share

The Quantum bits are also known as qubits. It consists of quantum information and it is quite long. It has been based on the efforts of foreign research team. There are researchers who had improved the time of retention. There is coherence time of 10 milliseconds. This is 10,000 times greater than record previously. It adds the orbital motion along with spinning within the atom. This boost in the retention of information had a lot of implications. It is meant for the development of information technology. The coherence time is quite long and there are spin-orbit qubits. This is the right candidate for creating the big quantum computers. The report has been published in the Nature Materials in the edition of 20th July.

The spin-orbit qubit has been utilized in the charged particle. It seems to be a hole. The impurity atom had trapped it within the silicon crystal. Dr. Takashi Kobayashi is the primary researcher at University of New South Wales Sydney along with the assistant professor from the Tohoku University. The Orbital motion along with the spinning of that hole has been coupled with locking. There are meshing gears and there is spinning and circular motion. They have been locked at one place.

There is an encoding of the Qubits. An orbital motion has been used in that charged particle. It created a number of advantages which is in great demand for creating the quantum computers. In order to use benefits of qubits, there is a team of researchers along with Kobayashi who utilized the exotic charged particle named "hole" within silicon. The goal is to state the qubit, from the orbital motion. There are spin of holes within the silicon and they have been coupled at one point.

There is an encoding of Spin-orbit qubits through holes. They are quite sensitive for the electric fields. As per Kobayashi, it permits quick control along with the benefits who had increased in the quantum computers. Qubits have been influenced by the electrical noise. It had created a limitation in the coherence time.

The work has been assisted by ARC Centre of Excellence for Quantum Computation and Communication Technology, along with U.S. Army Research Office. It has been supported by the Tohoku University Graduate Program in the field of Spintronics.
