The thing about quantum computers is that they are super powerful. They can solve problems that regular computers cannot. Regular computers use bits that’re either 0 or 1. Quantum computers use something called qubits. These qubits can be things at the same time. This makes them really good at solving problems.
There is a problem. Quantum computers are really hard to make. They need equipment and they have to be really cold. They also cost a lot of money. That is why there are no quantum computers in the world. That is why not many people can use them.
A New Way To Do Things
Some researchers from the Henan Key Laboratory of Quantum Information and Cryptography and Nanyang Technological University have found a way to make quantum computers more accessible. They made something called surrogates. These are like computer models that can act like quantum computers.
These models learn how a quantum computer works. Then they can do things like the quantum computer. They do not need the special equipment. They can just use a computer.
How It All Works
The predictive surrogate learns what happens when you put information into a computer. Then it can make predictions about what will happen in the future. It does not need to use the quantum computer
The researchers start by getting some information from a computer. Then the model looks at this information. Learn what the quantum computer does. After that it can make predictions about things. It can do all of this on a regular computer.
This is really good because it means that people do not need to use the quantum computer much. That saves time and money.
Testing The New Way
The researchers tried out their way with a real quantum computer. It had 42 qubits. They used the surrogate to do two important tasks. One was to help with chemistry and materials science. The other was to help with understanding how things behave when they are not in balance.
The results were really good. The predictive surrogate was very accurate. It did not need to use the quantum computer very much. This means that people can do things faster and cheaper.
Why This Matters
One of the problems with quantum computers is that they are not accessible. Not many people can use them.Predictive surrogates could change this. They could let people use quantum computers without having one.
This could help with things like chemistry and physics. It could make quantum research cheaper. Because people would not need to use quantum computers as much.
What Comes Next
The researchers want to keep working on surrogates. They want to make them better and use them for things. They also want to use them with quantum computers that can fix their own mistakes.
They hope that predictive surrogates can help make quantum computers more practical and affordable. They hope that this can help more people use quantum computers. Quantum computers are still really new. Predictive surrogates could be an important step towards making them more useful.
