Mid-circuit measurements are one of the biggest practical hurdles in quantum error correction on encoded qubits. Researchers in Innsbruck and Aachen have now proposed and experimentally demonstrated ...
The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, ...
ABSTRACT: Grover’s algorithm achieves O( N ) query complexity for unstructured search, a result proven optimal by Zalka for algorithms using a fixed oracle operator. This paper presents the ...
You’re late for an important appointment. Just as you are leaving your house, you realise your phone is flat. Imagine you could charge it almost instantly by exploiting the strange rules of quantum ...
IBM is betting on hybrid systems being the future of near-term quantum computing, introducing a new computing architecture that uses both classical and quantum-specific technology to apply the ...
D-Wave will help more companies streamline their workflows. IonQ aims to build smaller, more accurate systems using its “trapped ion” technology. QCi’s photonic chips could make it easier to ...

The stock prices of the so-called Quantum Four are back on the rise today, after already accruing significant gains yesterday as well. The upward trend is a reversal for IonQ, D-Wave, Rigetti, and ...
Estimating the number of solutions to search problems using quantum phase estimation (QPE) on the Grover operator. The Grover operator's eigenvalues encode the solution count, which QPE extracts.
