New discoveries about quantum computers could help accelerate the development of the quantum internet

The tech world is eagerly awaiting the arrival of working quantum computers and the benefits they promise to bring.

From speeding up computations to running multiple algorithms simultaneously, quantum computers can help solve some of the toughest problems facing scientists today.

For these special computers to work, they must harness quantum power. the internet Connect these computers. But creating a quantum internet is complicated because the technology is so fragile.

But the scientist from Simon Fraser The university recently said it found a missing piece in the development of the quantum internet. It is a unique property of silicon qubits never seen before.

With these new observations, scientists hope to ease the development of what many say will usher in a new technological age.

Background: How do quantum computers work?

Quantum computers, instead of using ordinary computer bits, qubit, the basic information component of the system. These qubits are tangle, Allows for better synchronization between qubits. This allows quantum computers to run more efficiently. But the technology is far from perfect.

Qubits are susceptible to external noise, greatly complicating the system FragileAdditionally, many types of qubits need to be kept cool (almost 0K) to function, making the system more costly.

Many quantum companies are striving not only to create working quantum computers, but also to create methods for error correction in their computations. However, longer lasting qubits are needed for better error correction and ultimately more stable quantum systems.

Researchers at Fraser Simon University say they may have found a solution to this problem.

Analysis: Qubits to Power the Quantum Internet

A qubit has a finite amount of time in an analyzable state. External noise can also tamper with this readable state and make it even shorter.

To keep this state open longer, researchers at Simon Fraser University analyzed Silicon qubits, some of the most stable qubits in use today.

Scientists have been able to identify specific regions of silicon qubits. T center, which helps stabilize it. T. Centers can connect qubits either spin-aligned or in the direction the qubits are facing.

According to Silicon Quantum Technologies’ Canada Research Chair, Stephanie Simmons: “This work is the first to measure a single T center in isolation, and in fact the first to measure any single spin in silicon solely by optical measurements.”

T-centers not only help qubits synchronize through the same spin alignment, they can also emit light at the same wavelengths that current fiber optic cables use. This makes it a clear choice for developing the quantum internet.

“With T. centers, we can build quantum processors that essentially communicate with other processors,” Simmons explains. “If silicon qubits could emit photons (light) and communicate in the same bands used in data centers and fiber networks, then connecting the millions of qubits needed for quantum computing would You get the same benefits.”

The researchers hope that these newly discovered T. centers will also help scale quantum computers into more powerful machines and make them more accessible to the public.

Prospects: Better connectivity for quantum computers

Quantum computers seem inaccessible to most people today, but are expected to become more accessible in the future.

Since silicon computer chips are already relatively cheap to manufacture, using silicon qubits could make these computers cheaper to manufacture. Moreover, silicon qubit research has progressed further since then. 2019when Google partnered with NASA announce the goal of achieving quantum hegemony.

“By finding a way to create quantum computing processors in silicon, we are leveraging years of development, knowledge and infrastructure used to manufacture traditional computers, rather than creating a whole new industry for quantum manufacturing. You can,” Simmons said.
