Mobile qubits on a chip move us a step closer to everyday quantum computers

Phys · · 595 words · By Paul Arnold

Researchers from Delft University of Technology have developed a method to move qubits across a silicon chip using 'conveyor-mode shuttling.' The study, published in Nature, demonstrates two-qubit operations and quantum teleportation, potentially addressing the limitation of fixed qubits in quantum computing.
