It has been designed for high efficiency when manipulating large Pauli operators -- addition, multiplication, Clifford/general rotations, commutativity/contextuality checks, symmetry generation, basis reconstruction and subspace projections have all been reformulated in the symplectic representation and implemented carefully to avoid unnecessary operations and redundancy. It also has a QASM simulator for evaluating expectation values, which is efficient when restricted to Clifford operations. -### What can Symmer do on a standard i5 laptop in just _one_ second? +### What can Symmer do on a standard laptop in just _one_ second? - Evaluate the expectation value of a 1,000-qubit Clifford circuit with a depth of 2,000. -- Perform a unitary rotation of a 100-qubit Pauli operator with 1,000,000 terms. -- Square a 100-qubit Pauli operator with 1,000 terms, involving a cleanup procedure over 1,000,000 cross terms. +- Perform a non-Clifford unitary rotation of a 1,000-qubit operator with 100,000 Pauli terms. +- Square a 1,000-qubit operator with 500 Pauli terms, involving a cleanup procedure over 250,000 cross terms. - Multiply two 100,000,000-qubit Pauli terms together.
