IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum ...

The alternative text for this image may have been generated using AI. We vary the number of layers from 4 to 256 and compare the survival probability of the unencoded circuits and the circuits encoded ...

As high-speed analog-to-digital converters (ADCs) have increased in sampling rate, so has the problem of code errors — also known as sparkle codes — in the ADC ...

Computers employ a variety of schemes to check whether a chunk of digital information–transmitted as a message, stored in a database, or functioning as a set of instructions–remains error-free. Such ...

The experiments reported here leverage two recent advancements in gate calibration on the Sycamore architecture. First, we use the reset protocol introduced in ref. 35, which removes population from ...
