New Qubits More Stable?

Advances in stable solutions.

A superconducting microwave resonator (gold curves) can use microwaves (pale beam) to help control a single isolated electron (orange waves) trapped on a block of solid frozen neon (green block). The individual electrons, controlled by the microwave pulses, can then be harnessed as individual qubits to make a new kind of quantum computer, according to a new study in the journal Nature.

Quantum computers can theoretically find the answers to problems no classical computer could ever solve, but they rely on infamously unstable components known as qubits. New findings now suggests that electrons trapped on frozen solid neon could prove a simple yet powerful kind of qubit for use in future quantum computers.

Qubits, or quantum bits, rely on the bizarre nature of quantum physics, which suggests that electrons, atoms and other building blocks of the universe can exist in a state known as superposition where they are essentially spin in two opposite directions at once or exist in two or more places at the same time. By placing many qubits into superposition, a quantum computer can in theory perform a mind-boggling number of computations simultaneously.

Amazon, Google, IBM, and many others are racing to create a practical quantum computer from a variety of qubit platforms, such as superconducting loops, electromagnetically trapped ions and spins within silicon. However, all qubits are extraordinarily fragile to outside interference ..... "
