Amazon announces next-generation Ocelot quantum computing chip.

On February 27th, Amazon Web Services (AWS), a subsidiary of online retail giant Amazon, launched a new generation quantum computer chip called Ocelot, with the ambition of significantly shortening the development time for a commercially viable quantum computer.

Ocelot is a prototype quantum chip that uses "cat" qubits, an advanced technology that significantly reduces the number of physical qubits (the basic computing units of quantum computers) needed to perform complex calculations. The "cat" qubit, also known as the "Schrödinger's cat," is named after physicist Erwin Schrödinger's thought experiment, which hypothesized a cat being simultaneously considered dead and alive when confined in a box containing radiation. In physics, this is a quantum superposition, meaning a quantum system can exist simultaneously in multiple different states until measured.

Thanks to this "cat" qubit, the Ocelot chip only needs 9 physical qubits to create a "logic" qubit—a qubit that has been corrected for errors to serve useful computations. Meanwhile, traditional methods require approximately one million physical qubits to create a "logic" qubit.

According to AWS, this technology could shorten the development process of quantum computers with practical applications by up to five years, bringing specific benefits to industries such as pharmaceuticals, finance, materials science , and artificial intelligence.

Quantum computers promise to perform calculations that would take millions of years to accomplish with traditional computers. Therefore, quantum computers could accelerate research in fields such as the development of new materials and pharmaceuticals. However, to realize this potential, scientists need to overcome the limitations of qubits regarding errors and their stable operation.

Ocelot was introduced at the same time AWS published research in the scientific journal Nature, reflecting significant advances in the field of quantum computing. Recently, many major technology companies such as Google, Microsoft, and PsiQuantum have also continuously announced new achievements in this field.
