A topological quantum computer is a theoretical type of quantum computer proposed by Russian-American physicist Alexei Kitaev in 1997. [2] It utilizes quasiparticles , known as anyons , in two-dimensional systems.

Microsoft is building topological qubits that store quantum information in the two ends of a superconducting nanowire. These qubits are less sensitive to noise at either end individually. Microsoft’s recent paper shows measurements and analysis that demonstrate this topological phase in devices that will form the basis of a qubit.

Mar 14, 2022 · Building on two decades of scientific research and recent investments in simulation and fabrication, the Azure Quantum team has engineered devices that allow them to induce a topological phase of matter bookended by a pair of Majorana zero modes.

Oct 3, 2024 · Qubits have generally been categorized into three types: physical, logical, and topological. These are differentiated based on theoretical concepts, function, and how they are implemented on quantum computing hardware.

Jun 18, 2023 · Google Quantum AI researchers inspect the arrays of superconducting circuits that comprise the system they used to develop a new method of what's called topological quantum computation.

Nov 26, 2024 · Researchers from, Quantinuum, Harvard and Caltech have created what they are referring to as the first-ever experimentally demonstrated “true topological qubit,” using a Z₃ toric code to encode quantum information in a way that is more resistant to errors.

Mar 14, 2022 · We have discovered that we can produce the topological superconducting phase and its concomitant Majorana zero modes, clearing a significant hurdle toward building a scaled quantum machine.

Sep 6, 2018 · When applied to quantum computing, topological properties create a level of protection that helps a qubit retain information despite what’s happening in the environment. The topological qubit achieves this extra protection in two different ways: Electron fractionalization.

May 5, 2022 · Topological qubits promise lower error rates than conventional qubits, and as such can perform scalable quantum computation at lower overhead. On top of that, in these papers we introduce a new class of quantum error correction codes, called Floquet codes, which are particularly suited to topological qubits.

3 days ago · A quantum bit (qubit) can be abstracted into a two-level system, the physical implementation of which can be based on superconducting circuits, semiconductor dots, ion traps, optical photons and ...
