Before the quantum era officially begins, scientists must first prove that quantum computers are superior to today’s classic computers. That’s why IBM researchers recently conducted experiments to do that.
For the first time, a new blog post from IBM Quantum, the company’s researchers reported a simultaneous proof with an experimental test of a new kind of quantum superiority. Specifically, we have shown that even today’s noisy cubits offer “more value than bits as a medium of storage during computation.”
IBM’s quantum team is thinking about computing from a circuit perspective, and at the beginning of the circuit there are some classic or qubits. These bits are set to their initial values and the circuit travels forward through a user-written program consisting of gates. Different gates have different effects on these bits, but the output of this type of circuit is a set of 0s and 1s in both the classical and quantum cases.
For traditional computers, these bits are switches that can be turned on or off and interact within the gate to toggle the switch based on the input to this gate. However, a qubit or qubit can take a combination of these two switch positions, and the quantum gate creates a state that incorporates all possible combinations of switch positions.
In a new academic paper published in Nature Physics, “Quantum supremacy in calculations in confined spacesResearchers at IBM Quantum sought to prove that quantum computers are superior to traditional computers.
They did this by setting up an experiment with a circuit that was restricted to the use of 2-input gates and limited to the use of 1-bit compute / scrap space and answering the following questions. Quantum scratch space? ”
Later, IBM researchers proved in a treatise that there are functions that cannot be calculated on a limited classical computer, but can be calculated on a limited quantum computer. To do so, they compared real quantum computers with classic computers.
To increase the computational power of the classic computers used in the experiments, researchers armed computers with random access to boulesgates. However, according to a study in an IBM treatise, even with access to this randomness, traditional computers had only an 87.5% chance of success, while a complete, noise-free quantum computer had a 100% chance of success. I was successful.
Quantum computers today are too noisy to achieve this kind of perfect result, but IBM Quantum researchers have achieved a success rate of 93% by adjusting special entangled gates to perform these. And defeated the traditional system when running the actual experiment. Circuit more efficiently.
