Revolutionary approach could ‘speed up’ quantum computers

According to a study published in the scientific journal Physical Review, a research team has developed a new theoretical approach to revolutionary hardware that opens the doors to a new model of quantum computing. In simpler language, The approach suggests that it is possible to process a variety of real-world problems faster than today’s traditional quantum computers.

The new strategy uses a simple magnetic field to spin the qubits of the quantum computer; unlike the traditional situation where a full system of multi-qubit logic gates has to be configured. Therefore, scientists believe that the approach could solve the current practical problems of quantum computers.

What is a qubit?

A qubit is a quantum bit, an analog version of a binary bit in a conventional computer. For example, a binary bit represents the value ‘0’ or ‘1’, while the qubit enters a superposition state and represents a ‘0’, ‘1’ or any ‘0 and 1’ value.

Scientists describe the new strategy can solve a number partitioning problem faster than today’s quantum computers; in this case, using Grover’s algorithm. Also, since the technique relies on natural entanglement, it requires less connections between qubits; however, in a common quantum operation, induced entanglement is used and more coupling is needed between qubits.

“Our discovery removes many of the stringent requirements for quantum hardware. Natural systems, such as the electronic spins of defects in diamonds, have interactions that are exactly necessary for our computational process,” said Nikolai Sinitsyn, a theoretical physicist at Los Alamos National Laboratory in the United States and co-author of the paper. has,” he said.

The future of quantum computing

Quantum computers exploit the potential of quantum mechanics to significantly increase data processing power.. Despite this, it is important to emphasize that all existing quantum PCs remain under scrutiny; that is, it is an area that is still in its infancy compared to traditional computers.

In an interview with the website podcast IFLscienceWinfried Hensinger, professor of quantum technology at the University of Sussex in the United Kingdom, said quantum computing is advancing rapidly; He explains that 10 years ago no one would find a job in the region, but today it is possible.

“Because nobody thought it was worth it, because people didn’t think we could make a machine like this. You’re going to see a lot of new applications in the next five or 10 years. Now we’re talking about simulating molecules and drug discovery or code cracking; In 10 years we will talk about very different things”, said Hensinger.
