Can we speed up ResourcesEstimator / QCTraceSimulator?

2

**Please describe what you would like the feature to accomplish.** Q# is probably one of the most promising tools for resource estimation of FT algorithms. However, from an initial assessment,...

Add a classical simulator to Cirq

12

The feature request is to add a classical simulator which can simulate X / CNOT and multi-controlled X gates, similar to `ToffoliSimulator` in Q# See https://docs.microsoft.com/en-us/azure/quantum/machines/toffoli-simulator cc @mpharrigan to add...

Add `name` to `cirq.CircuitOperation` to help when printing circuit diagrams

4

**Is your feature request related to a use case or problem? Please describe.** `cirq.CircuitOperation` is useful to wrap circuits in an operation and thus build nested circuits. However, when printing...

Move cirq-core/contrib out of cirq-core as a separate vendor package.

3

Post 1.0, cirq-contrib is expected to follow versioning policy similar to other vendor packages outside of cirq-core. We also ideally don't want cirq-core to depend on anything present in cirq-core/contrib....

Add analytical decomposition for synthesis of single qubit unitaries generated by Clifford and T gates.

2

**Is your feature request related to a use case or problem? Please describe.** One of the promising gatesets for fault tolerant regime is the Clifford + T gateset, where executing...

`Xa*Zb*Zb*Zb` works but `Xa*Zb**3` raises error

2

**How to reproduce the issue** ```python In [1]: import cirq ...: a, b = cirq.LineQubit.range(2) ...: Xa, Zb = cirq.X(a), cirq.Z(b) ...: print(Xa * Zb * Zb * Zb) #...

Add sparse representation support to `cirq.DensePauliString`

2

**Is your feature request related to a use case or problem? Please describe.** `cirq.PauliString` drops identity gates by default and only stores non-identity terms. Therefore, a pauli sum hamiltonian $H$...

Add confusion maps support to PauliMeasurementGate

16

https://github.com/quantumlib/Cirq/pull/5480 added support for confusion maps to measurement gates. The feature request is to extend this support to `cirq.PauliMeasurementGate` as well. P2 - we should do it in the next...

[Needs to be scoped] General single qubit parameterized gate compiler

10

**Is your feature request related to a use case or problem? Please describe.** A general single qubit parameterized gate compiler was proposed as a compilation building block in #3239. This...

Create GCP setup to run ASV benchmarks and host the output website

4

**Is your feature request related to a use case or problem? Please describe.** [PR3822](https://github.com/quantumlib/Cirq/pull/3822) adds performance benchmarks for ASV to solve #1124 . Create a setup on GCP to run...
