The researchers believe their model will be able to process more than a million qubits

A pair of University of Tokyo researchers say their new approach to quantum computing should allow quantum computers to perform a far greater number of computations than other types of quantum computers.

Akira Furusawa and Shuntaro Takeda at the University of Tokyo in Japan say they have developed the "ultimate" quantum computing method.

Their technique's core element is a basic optical quantum computing system that employs photons as quantum bits (qubits), created in 2013.

The machine can only accommodate one light pulse, and boosting its capabilities typically entails linking several such devices together. However, Furusawa and Takeda circumvented this by making one machine handle multiple light pulses via a loop circuit.

Theoretically, multiple pulses laden with data could traverse the circuit indefinitely, enabling the circuit to execute multiple tasks and to switch from one task to another via instant manipulation of the pulses.

Furusawa and Takeda say a single circuit of theirs can accommodate more than 1 million qubits, and Furusawa says the next phase is "to develop the hardware, now that we've resolved all problems except how to make a scheme that automatically corrects a calculation error."
