The researchers have achieved something simply beyond a sci-fi movie. For the first time, they have linked isolated groups of particles – called time crystals – into a single, growing system that could be hugely useful in quantum computing. A team of physicists, working with Samuli Autti of Lancaster University, has successfully paired two time crystals to create a ‘two-state system’, also known as a ‘two-level system’ ‘. This could open a new avenue for quantum computers to use time crystals as qubits.
Time crystals, which are considered to be practically impossible to create until they discovered in 2016. They were first hypothesized by Nobel laureate scientist Frank Wilczek in 2012. These time crystals are Was observed interacted for the first time in 2020 by the same team from Lancaster University. At the time, however, no one could have thought of linking these crystals in such a way that they could be used as qubits from Quantum Computing.
Time crystals are similar to ordinary crystals, like metals or stones, but with a special property. In normal crystals, the atoms are arranged in a fixed, 3D lattice structure. In a time crystal, the atoms exhibit patterns of motion over time that cannot be easily explained by an external repulsion. These oscillations – called “ticks” – are locked to a specific and regular frequency.
The main reason physicists believe that creating time crystals is considered impossible is because their atoms are in perpetual motion that seems to defy the laws of physics. However, quantum physics Not only have they helped create time crystals, but the scientists have also demonstrated that these crystals have the potential to power useful devices.
“Everybody knows that perpetual motion of machines is impossible. However, in quantum physics, perpetual motion is okay as long as we keep our eyes closed. By sneaking through this crack, we have can create time crystals”. speak Physicist and lead author Samuli Autti of Lancaster University in the UK.
Time crystals were first observed using helium-3, a rare isotope of helium with one missing neutron. The team cooled the superfluid helium-3 to -273.15 degrees Celsius. The researchers then created two time crystals inside the superfluid and brought them close together. They then observed two time crystals interacting with each other.
The researchers published their findings in the journal Nature Nature Communications.
