Entangled Particles Advance Quantum Computing

One of the most gifts to the humankind is technology. It had helped people ways of living in different aspects. It made people life more comfortable and easier. In generation of computers today, physicist used burst of radio waves to create billions of quantum- entangled pairs of sub atomic particles in silicon. The study offers a future computing world in which individual atomic nuclei can store and retrieve data and dingle electrons shuttle it back and forth.

The study led by physicist john Morton of Oxford University and Kohei Itoh of Keio University, they describe about bombarding a three dimensional crystals with microwave and radio frequency to make the entangled pairs. The quantum computing equivalent of today’s transistor is one of a range of competing approaches to qubits.
The basis of transistor to store information is whether they are on or off. In the study, qubits can store information in the form of orientation, or spin of an atomic nucleus or an electron. The storage ability is depends on entanglement which changes one particle that affects another particle. This study has a significant potential because it might permit quantum computer designers to exploit low cost and easily manufacturable technologies now used in electronics industry.

The researchers of the study had used quantum-entangled pairs of atomic nuclei and electrons in which particles are link so that measuring a property of one instantly reveals information about the other, no matter how far apart the two particles are to extract information. The group hopes to create quantum computing system by moving the electrons tangled them with another nucleus.

According to Dr. Morton “ We would move the electron from the nuclear spin it is on the neighboring nuclear spin” and “that shifting step is what we really now need to show works while preserving entanglement.
The group believes that one of the principal advantage of the new silicon- bade is that it will be able to maintain the entangled state to preserve quantum information in long period of time.
“To a member of the general public that still sounds like a lousy computer memory” Dr. Morton said. “But for quantum information the lifetime of a second is very exciting, “because there are ways to refresh data.
