## CirQ Quantum programmming
CirQ is a python framework for creating, editing, and invoking Noisy Intermediate Scale Quantum (NISQ) circuits.
Install
```bash
python3 -m pip install --upgrade pip
python3 -m pip install cirq
```
dependencies
For witing to pdf
```bash
brew cask install mactex
```
### Circuis
Can be either
- **Circuit**
Circuit is a collection of Moments. A Moment is a collection of Operations that all act during the same abstract time slice.
- **schedule**
Schedules offer more control over quantum gates and circuits at the timing level
Cirq has three main ways of defining qubits:
- cirq.NamedQubit: used to label qubits by an abstract name
- cirq.LineQubit: qubits labelled by number in a linear array
- cirq.GridQubit: qubits labelled by two numbers in a rectangular lattice.
## Variational quantum algorithms
The variational method in quantum theory is a classical method for finding low energy states of a quantum system.
In classical variational method to a system of n qubits, an exponential number (in n) of complex numbers are necessary to generically represent the wave function of the system.
However with a quantum computer one can directly produce this state using a parameterized quantum circuit, and then by repeated measurements estimate the expectation value of the energy.
