Control of Spin Qubits at Near Absolute Zero Provides Path Forward for Scalable Quantum Computing

Control of spin qubits at near absolute zero provides path forward for scalable quantum computing

Developing technology that allows quantum information to be both stable and accessible is a critical challenge in the development of useful quantum computers that operate at scale. Research published in the journal Nature provides a pathway for scaling the number of quantum transistors (known as qubits) on a chip from current numbers under 100 to the millions needed to make quantum computation a practical reality. The result is enabled by new cry

Breakthrough Qubit Control Near Absolute Zero Is Scalability Game-Changer For Quantum Computing

If you want to make a real quantum computer with a million qubits, this is what you need.

Robust Tripartite Entanglement In Spin Qubits Despite Spatial Noise.

Researchers demonstrate the sustained generation of robust, long-lived tripartite entanglement within a triangular spin-qubit system despite spatially correlated noise, revealing that environmentally induced coherent coupling is surprisingly less critical than in two-qubit systems and highlighting post-selection and coherent driving as effective methods for enhancing entanglement fidelity for potential quantum computation applications.

Control of Spin Qubits at Near Absolute Zero Could Enable Million Qubit Quantum Computers

David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), the temperature at which – theoretically – matter ceases moving. Experts think that spin qubits (where information is encoded onto the magnetic direction of single electrons) ...
