A Record was Broken in Quantum Computers: By 100 Times

Google's quantum computer called Sycamore was previously the world's most powerful quantum computer. A new quantum computer shattered this record and set a new peak. Moreover, the new quantum computer consumes 30 thousand times less power. 

Computer engineers and scientists at Quantinuum conducted several experiments using the new 56-qubit H2-1 computer. In these experiments, the device was operated at different levels and with different qubits. The performance record of quantum computers was also broken in the studies. 

To unlock the quantum computer's potential, the researchers tested it with a standard algorithm that shows how error-prone the qubits are or how noisy the results are. 

Quantum computers can perform parallel processing as well as being able to perform more operations thanks to qubits. Traditional computers perform operations sequentially. Adding more qubits to the system also increases the machine's potential exponentially. So, when we add 5 more units to 5 units, we get 25 units of computing power, not 10 units. 

The point at which quantum computers surpass conventional computers is called “quantum supremacy.” To achieve this computational capacity, a machine with 1 million qubits is required. The most powerful machine today has a computing power of approximately 1000 qubits. The reason for this is that they are error prone and most of the processing power is used for error correction. The new quantum computer performed 35 percent of transactions without errors.
