Electron pairing in quantum dots as a new approach to qubit research
The next step in qubit research is being taken by scientists from QuTech that
One of the building blocks of a quantum computer is Qubits
A conventional computer uses bits that can be either zero or one. A quantum computer, on the other hand, uses quantum bits or "Qubits."
Qubits can be photons, electrons, or any system that can exist in so-called quantum states. It allows you to hold more information and access more computing power because these states can exist at the same time
This can be used in calculations with many different outcomes, such as medical research or materials science
One of the promising candidates as the building block of a future quantum computer is a topological qubit, based on pairs of equal-spin electrons
Although pairs of electrons with opposite spins can be found in most naturally occurring superconductors, materials hosting
Cooper pairs made of equal-spin electrons have been much harder to engineer in a controlled way, despite promising progress
One of the main authors of the publication in Nature is a researcher at QuTech, a collaboration between the TNO and the TU Delft
The researchers have been able to demonstrate the existence of an equal-spin pair by using quantum dots in a nanowire. Our results show a controllable detection of pairs between the quantum do
A so-called artificial Kitaev chain of several quantum dots, which is a promising method towards using topological qubits, requires a sequence of quantum dots to bepaired
