Can quantum computer work at room-temperature?

Quantum computers are hot today, because of their mind boggling computing capacity that can better the best of existing supercomputers. They use the quantum phenomenon of superposition. However, quantum phenomena do not work at room temperature.

Is it possible to achieve room temperature superconductors?

A room-temperature superconductor is a material that is capable of exhibiting superconductivity at operating temperatures above 0 °C (273 K; 32 °F), that is, temperatures that can be reached and easily maintained in an everyday environment.

Do quantum computers use superconductors?

Superconducting quantum computing is an implementation of a quantum computer in superconducting electronic circuits. More than two thousand superconducting qubits are in a commercial product by D-Wave Systems, however these qubits implement quantum annealing instead of a universal model of quantum computation.

What would happen if we had room temperature superconductors?

While some cryogenically cooled systems currently leverage this, a room-temperature superconductor could lead to an energy-efficiency revolution, as well as infrastructure revolutions in applications such as magnetically levitated trains and quantum computers. A modern high field clinical MRI scanner.

What temperature does a quantum computer need to be?

Typically, qubits operate at 20 millikelvin, or about -273 degrees Celsius – temperatures that are even colder than outer space.

How do high temperature superconductors work?

High-temperature superconductivity, the ability of certain materials to conduct electricity with zero electrical resistance at temperatures above the boiling point of liquid nitrogen, was unexpectedly discovered in copper oxide (cuprate) materials in 1987.

Why do quantum computers need superconductors?

The physical implementation of qubits and gates is difficult, for the same reasons that quantum phenomena are hard to observe in everyday life. One approach is to implement the quantum computers in superconductors, where the quantum effects become macroscopic, though at a price of extremely low operation temperatures.

How does a flux qubit work?

A typical flux qubit is made by joining three Josephson junctions with superconducting leads to form a closed loop and using an applied magnetic field (perpendicular to the loop) to drive the circuit by controlling the phase (see figure 1c).
