Big Blue Plans to Deliver 4,000+ Qubit System

IBM’s work to usher in an era of practical quantum computing will leverage three pillars: robust and scalable quantum hardware; cutting-edge quantum software to orchestrate and enable accessible and powerful quantum programs; and a broad global ecosystem of quantum-ready organizations and communities.

Quantum Volume 4096 Anyone?

Quantinuum has reached another milestone in its quest to build the highest performing quantum computer in the world.

How to Cope With the Side Effects of Quantum Error Correction

It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results — and shows how to rectify these shortcomings.

Silicon-Based Qubits Very Similar in Design to Classic Silicon Transistors

“Hot” spin quantum bits in silicon transistors   Quantum bits (qubits) are the smallest units of information in a quantum computer. Currently, one of the biggest challenges in developing this kind of powerful computer is scalability. A research group at the University of Basel, working with the IBM Research Laboratory in Rüschlikon, has made a […]

The Physical Speed Limit of Computers Is…

The maximum speed of signal transmission in microchips is about one petahertz (one million gigahertz), which is about 100,000 times faster than current transistors. Whether computer chips of this maximum speed can ever actually be produced is, however, questionable.
