The power of quantum computing technologies is based on the fundamentals of quantum
mechanics, such as quantum superposition, quantum entanglement, or the no-cloning …

A practical quantum computer must not merely store information, but also process it. To
prevent errors introduced by noise from multiplying and spreading, a fault-tolerant …

Quantum computing technology has reached a second renaissance in the past five years.
Increased interest from both the private and public sector combined with extraordinary …

Fault-tolerant quantum error correction is a necessity for any quantum architecture destined
to tackle interesting, large-scale problems. Its theoretical formalism has been well founded …

Quantum computing (QC) is at the cusp of a revolution. Machines with 100 quantum bits
(qubits) are anticipated to be operational by 2020 [30, 73], and several-hundred-qubit …

Quantum error correction (QEC) and fault-tolerant (FT) mechanisms are essential for reliable
quantum computing. However, QEC considerably increases the computation size up to four …

We present the first high performance compiler for very large scale quantum error correction:
it translates an arbitrary quantum circuit to surface code operations based on lattice surgery …

Quantum computers have recently made great strides and are on a long-term path towards
useful fault-tolerant computation. A dominant overhead in fault-tolerant quantum …

Experimental groups are now fabricating quantum processors powerful enough to execute
small instances of quantum algorithms and definitively demonstrate quantum error …

In this paper we outline a method for a compiler to translate any non fault tolerant quantum
circuit to the geometric representation of the lattice surgery error-correcting code using …
