#BinanceTurns8 Physicists from Aalto University have set a new coherence record for a transmon qubit - over 1 ms. This is almost double the previously recorded maximum of ~0.6 ms.

"We have just recorded coherence of over a millisecond, with a median value of half a millisecond," commented researcher Mikko Tuokkola.

The coherence of a qubit is a key parameter for the performance of quantum computers. The longer it lasts, the more computations can be performed before errors begin to accumulate. This reduces the burden on error correction systems and brings us closer to the creation of a 'silent' quantum computer.

The qubit was created by scientists from the Quantum Computing and Devices (QCD) group at the Department of Applied Physics at Aalto University. A superconducting film from the VTT Technical Research Centre of Finland was used to manufacture the chip.

According to QCD head Professor Mikko Möttönen, this achievement is an important milestone for scaling quantum systems. It paves the way for increasing the number of qubits, reducing noise, and overall enhancing the stability of future machines.
