This type of encoding offers two key advantages, according to the researchers. In what’s referred to in quantum computing parlance as a neutral atom modality, the Phoenix encodes quantum information - the qubit states |0> and |1> - in two of the nuclear spin states of a single, uncharged strontium atom. “It’s important because longer coherence times mean fewer limitations on running deep circuits, and error-correction schemes have more time to detect and correct errors through mid-circuit measurements,” they added. Longer coherence times offer several advantages for quantum computers, according to the team. Coherence, which refers to how long a qubit maintains its quantum state or encoded information, is an important step in developing useful quantum computers, according to the Atom Computing blog. In a study published recently in Nature Communications, the team observed coherence in excess of 100,000 times the current length of the operations. The slightest disturbance - a gabby co-worker, or, in the case of qubits, an annoying cosmic ray or magnetic field - can throw off their concentration and destroy their ability to get work done.įor quantum scientists, keeping a qubit in that splendid isolation is called coherence - and the longer they can keep qubits in coherence, the better the chance that the infinite genius of qubits can be tapped to perform useful calculations.Ī team of researchers from Atom Computing now reports record coherence times for their quantum computer, dubbed Phoenix. Think of qubits as delicate geniuses who need perfect quiet and isolation to do their best work.
