Quantum processors are difficult to compare due to the different architectures and approaches. Due to this, published physical qubit numbers do not reflect the performance levels of the processor. This is instead achieved through the number of logical qubits or benchmarking metrics such as quantum volume , randomized benchmarking or circuit ...
Quantum cryptography, which relies on the principles of quantum mechanics, offers the possibility of secure communication channels that are resistant to eavesdropping. Quantum key distribution (QKD) protocols, such as BB84, enable the secure exchange of cryptographic keys between parties, ensuring the confidentiality and integrity of communication.
Google prompted controversy [7] [8] by claiming that the success of Willow "lends credence to the notion that quantum computation occurs in many parallel universes, in line with the idea that we live in a multiverse, a prediction first made by David Deutsch."
Sycamore is a transmon superconducting quantum processor created by Google's Artificial Intelligence division. [1] It has 53 qubits. [2] In 2019, Sycamore completed a task in 200 seconds that Google claimed, in a Nature paper, would take a state-of-the-art supercomputer 10,000 years to finish. Thus, Google claimed to have achieved quantum ...
www.ibm.com /quantum /blog /quantum-roadmap-2033 IBM Condor is a 1,121- qubit quantum processor created by IBM , unveiled during the IBM Quantum Summit 2023, which occurred on December 4, 2023. It is the 2nd largest quantum processor (in terms of qubits), just shy of the 1,125-qubit quantum processor by the company Atom , created in October 2023.
IBM Eagle is a 127-qubit quantum processor. [1] [2] IBM claims that it can not be simulated by any classical computer.[3] [4] It is two times bigger than China's Jiuzhang 2. [5]It was revealed on November 16, 2021 and was claimed to be the most powerful quantum processor ever made until November 2022, when the IBM Osprey overtook it with 433 qubits.
IBM Quantum Platform (previously known as IBM Quantum Experience) is an online platform allowing public and premium access to cloud-based quantum computing services provided by IBM. This includes access to a set of IBM's prototype quantum processors, a set of tutorials on quantum computation, and access to an interactive textbook.
The current state of quantum computing [1] is referred to as the noisy intermediate-scale quantum (NISQ) era, [2] [3] characterized by quantum processors containing up to 1,000 qubits which are not advanced enough yet for fault-tolerance or large enough to achieve quantum advantage.
