QuTech's Andreev spin qubit

Is this Stable qubit a prime candidate for universal quantum computer?

Welcome Back!

So here is a story that gets me excited. This is why I cover emerging tech across A.I. spectrums and Quantum.

Two promising architectures for solid-state quantum information processing are electron spins in semiconductor quantum dots and the collective electromagnetic modes of superconducting circuits. What if you could marry the two?

• Researchers from QuTech improved the so-called "Andreev spin qubit" in a critical way and believe it can become a prime candidate in the pursuit of a perfect qubit.

• The new type of qubit is created in a more reliable and intrinsically stable way, compared to previous versions, by combining the advantages of two other types of qubits. The team has published their work in Nature Physics.

"Finally," says Bargerbos, "we demonstrated the first direct strong coupling between a spin qubit and a superconducting qubit, meaning that they could get the two qubits to interact in a controlled way.

We Lack of Universal Qubit

Unlike the world of conventional computers, where bits are based on very well established and reliable technologies, the perfect qubit has not been invented yet.

Let’s’ try to wrap our heads around this:
