In this experiment, a new two-qubit universal gate called the Sycamore gate is constructed and employed to generate random quantum circuits (RQCs), using a programmable quantum processor with 53 qubits. These computations were carried out in a computational state space of size 9×1015. ...
Julian Kellyat Google AI Quantum and his colleagues have demonstrated the concept on Google’s Sycamore quantum computer, with logical qubits ranging in size from five to 21 physical qubits, and found that logical qubit error rates dropped exponentially for each additional physical qubit. The...

这块芯片的代号叫“Sycamore”，用一种美国的悬铃木（有点像法国梧桐）来命名，芯片上还印了一片悬铃木...
Google’s computer, called Sycamore, has 54 entailed superconducting qubits, only 53 of which were reportedly working during the test. Still, it was able to achieve quantum supremacy. Despite the achievement, many experts say that it’s a bit too early to celebrate. While Sycamore might have ...
The Nature fiasco is not the first time Google’s hardware research has come under the microscope. Google, in 2019, claimed quantum supremacy, with quantum computers outperforming classical computers. Google argued that its 54-qubit system called Sycamore, in which the qubits are arranged in a 2D...
The Sycamore chip is made up of 54 qubits, and in this experiment a team of scientists from Google and the University of California Santa Barbara (UCSB) used 53 of those – one didn’t perform for whatever reason. These 53 qubits were entangled into a random, complex superposition state, ...
We estimate that on the Summit supercomputer at Oak Ridge National Laboratories, secondary storage allows the simulation of 53- and 54-qubit Sycamore circuits with high fidelity to arbitrary depth... In particular, for 20 cycles of the entanglement pattern ABCDCDAB, which is specifically designed ...
Google’s latest iteration of its quantum machine, theSycamore quantum processor, currently holds 70 qubits. This is a substantial leap from the 53 qubits of its earlier version. This makes the new processor approximately 241 million times more robust than the previous model. ...
