This milestone achievement is important because it marks the first time that logical qubits have been shown to outperform physical qubits — a critical step towards fault-tolerant quantum computers.

An error, in this model, can be any unwanted flip of a 0 into a 1 or vice versa, whether it’s due to a random fluctuation or deliberate tampering. Pravesh Kothari proved a new result about the limits ...

Model selection and associated issues of post-model selection inference present well known challenges in empirical econometric research. These modeling issues are manifest in all applied work but they ...

"This allows us to exploit the exact, efficient solutions for planar spin glasses. For non-planar graphs, such solutions are computationally intractable," explained the researchers.

Error correction of cells have been reviewed by researchers who have investigatred the importance of crosstalk and its effects, and propose an alternative model that suppresses erroneous initiation.

Can we use quantum computers to make music? Julian Kelly, director of quantum hardware at Google Quantum AI, calls this result “absolutely critical” for scaling towards a large-scale quantum computer, ...
