Now, researchers at Argonne National Laboratory have achieved a major milestone in this area by developing a new qubit type with a nearly thousand-fold increase in coherence time. This breakthrough could pave the way for the development of more powerful and scalable quantum computers in the future.
The new qubits are based on single electrons trapped in silicon carbide devices. Silicon carbide is a relatively inexpensive and commonly used material, which makes it a promising platform for scalable quantum computing.
The researchers were also able to demonstrate scale-up by coupling two qubits together. This is an important step towards building larger and more powerful quantum computers.
The research, which was published in the journal Nature Physics, is a major step forward in the race to develop quantum computers that can tackle real-world problems. Quantum computers have the potential to solve problems that are intractable for classical computers, such as designing new drugs and materials, and simulating complex quantum systems.
How the Qubit Breakthrough Works:
The new qubits developed by Argonne researchers are based on single electrons trapped in silicon carbide devices. Silicon carbide is a semiconductor material with a very wide bandgap. This means that it is very difficult for electrons to escape from silicon carbide devices, which makes them ideal for trapping single electrons.
The researchers trap the electrons by placing them in tiny cavities in the silicon carbide devices. The cavities are created using a process called nanofabrication.
Once the electrons are trapped, the researchers can control their quantum states using electric and magnetic fields. This allows them to perform quantum operations on the qubits.
The Significance of the Qubit Breakthrough:
The new qubit type developed by Argonne researchers is a major breakthrough in quantum computing. The nearly thousand-fold increase in coherence time is a significant improvement over previous qubit designs. This means that the new qubits can store quantum information for much longer periods of time, which is essential for performing complex quantum computations.
The demonstration of scale-up is also a major achievement. It shows that the new qubit type can be coupled together to build larger and more powerful quantum computers.
Overall, the research by Argonne researchers is a major step forward in the race to develop quantum computers that can tackle real-world problems.
Potential Applications of Quantum Computing:
