Watson Research Center, IBM – Quantum computers can be a lot better performance boosters over conventional computers, but scientists could never get a good lead to correct quantum circuit errors in the past. Now, scientists from Watson Research Center of IBM have successfully found out a new method for correcting all the errors on a quantum circuit.
Details of this study have been published in a reputed journal named Nature Communications.
What Improvements Can Users Expect:
The basic units called ‘bits’ in conventional computers are stored in the binary form i.e. 1s and 0s. If one information is 1, then it cannot be 0, and vice versa. But in the case of quantum computers, scientists have come up with new basic units called ‘qubits,’ and they can be both 0s and 1s at the same time.
Even though the scope of quantum computing is limitless, but the information available in this field is fragile. It can be affected by various factors such as electromagnetic radiation, heat and defects in materials. Controlling such factors in Quantum Computing is one of the most toilsome tasks that one can think of.
How To Inch Closer To Quantum Computing:
The team of researchers at IBM came across two quantum errors called phase flip and bit-flip. These errors are likely to occur in any quantum computer. According to the key author of the study, Jay Gambetta, scientists had come across these errors in the past, but could never detect them together.
The team of scientists has developed a one-quarter inch square chip on which it demonstrated error-protection protocols. These protocols were put on a quantum circuit that comprised of one square lattice of 4 superconducting qubits. Scientists at IBM claim that square shape circuit is more scalable than linear circuits.
Experts call it an evolutionary step and hope that it will pave the way for quantum computers in the near future.
