They broke the record of quantum memory

Scientists approached a little closer to the dream of quantum computers, and managed to maintain a quantum bit of information for a record time. Specifically, an international scientific team managed to maintain a stable fragile quantum state for 39 minutes at room conditions at 25 degrees Celsius for three hours at a temperature close to absolute zero! It is worth noting that the previous memory record was only 25 seconds at room conditions, and 3 minutes at very low temperature. According to the scientific team, after the new achievement it creates more possibility for really long term storage of quantum information in room conditions.

Quantum computing may in future revolutionize the field of computing, but the implementation meets many difficulties to be overcome, including the long-term storage in the memory of a future quantum computer information units (qubits instead of just bits). The qubits can simultaneously take 0 and 1, and thus the quantum computer is able to make multiple parallel calculations. Unfortunately, it is also highly unstable. The importance of the new record is just that scientists have been able to stabilize the quantum memory time almost 100 times greater than what they had achieved so far.

But the researcher Stephanie Simmons of the Department of Materials at Oxford University noted that work still many technical difficulties to overcome before it becomes feasible to run large scale quantum calculations. As said, the biggest hurdle is to place different qubits in different situations and to control the way they interact with each other ( in the new experiment all the qubits in the same state).
