Scientists from the Defense Advanced Research Projects Agency (DARPA) and several others around the world used Google Quantum AI hardware to develop the world’s first crystal.
As the scientist reported, time crystals have been speculated as a quantum state that continuously changes but uses no energy.
The experiment claims to have simulated the particle that may be the perfect superconducting material to help make quantum computing a reality. Scientists were able to create the time crystal for about 100 seconds using qubits (quantum computing version of the traditional computing bit) inside the core of Google’s Sycamore quantum processor.
Time crystals are captivating objects for physicists because they essentially avoid the second law of thermodynamics, one of the most foolproof laws in physics. They can move from one quantum state to another consistently without losing or using energy. It indicates that entropy (a rough analogue of the amount of disorder in a system) is always increasing.
The experiment is the result of teamwork between scientists and Google Quantum AI, a joint initiative of Google, NASA and the nonprofit Universities Space Research.
In the quantum world, objects behave as both point particles and small waves, with the magnitude of those waves in a given region of space representing the probability of finding a particle there. But random defects in the structure of a crystal or a programmed randomness in the forces of interaction between the qubits can cause the cancellation of the probability wave of a particle everywhere, except a very small region.
The Research Mechanics Report describes the creation of a special microscopic platform where a time crystal is surrounded by superconducting qubits, which can be considered the quantum equivalent of a classical bit and the main driving force behind quantum computers. .
