Scientists have built a qubit, or quantum bit, that can achieve "quantum coherence" at room temperature — something normally only possible at temperatures close to absolute zero. To achieve quantum ...
Figure 1 Schematic diagrams of two superconducting flux qubit circuits. The conventional qubit (a) requires an external magnetic field to operate optimally, while the new flux qubit (b), using a ...
There’s a general consensus that performing any sort of complex algorithm on quantum hardware will have to wait for the arrival of error-corrected qubits. Individual qubits are too error-prone to be ...
AWS's first-ever quantum chip uses "cat qubits" to reduce errors exponentially as more qubits are added to a system. Scientists say it will lead to scalable and efficient quantum computers. When you ...
We’re nearing the end of the year, and there are typically a flood of announcements regarding quantum computers around now, in part because some companies want to live up to promised schedules. Most ...
Qubits are normally made from superconducting metals and need to be cooled to near absolute zero to avoid collapsing. But scientists just built an error-free "logical qubit" from a single laser pulse ...
Researchers used a 58-qubit quantum processor to realize and probe a Floquet topological phase, revealing exotic non-equilibrium matter beyond classical reach. (Nanowerk News) Unlike conventional ...
