For quantum computers to successfully solve real-world problems, it is necessary to tackle
the challenge of noise: the errors that occur in elementary physical components due to …

For the first time in history, we are seeing a branching point in computing paradigms with the
emergence of quantum processing units (QPUs). Extracting the full potential of computation …

Noise in quantum computers can result in biased estimates of physical observables.
Accurate bias-free estimates can be obtained using probabilistic error cancellation, an error …

To run large-scale algorithms on a quantum computer, error-correcting codes must be able
to perform a fundamental set of operations, called logic gates, while isolating the encoded …

The inevitable accumulation of errors in near-future quantum devices represents a key
obstacle in delivering practical quantum advantages, motivating the development of various …

Minimizing the effect of noise is essential for quantum computers. The conventional method
to protect qubits against noise is through quantum error correction. However, for current …

In the early years of fault-tolerant quantum computing (FTQC), it is expected that the
available code distance and the number of magic states will be restricted due to the limited …

Classical shadows enable us to learn many properties of a quantum state ρ with very few
measurements. However, near-term and early fault-tolerant quantum computers will only be …

The Eastin-Knill theorem states that no quantum error-correcting code can have a universal
set of transversal gates. For Calderbank-Shor-Steane codes that can implement Clifford …

One of the major challenges for erroneous quantum computers is undoubtedly the control
over the effect of noise. Considering the rapid growth of available quantum resources that …
