qramana is a TypeScript library for quantum calculation.
It attempts to make it easy for users to handle quantum computing.
These are qramana's features.
- Can handle qubit with only Qubit interface
- No need to consider synthetic quantum systems
- Can be implemented in JavaScript application (e.g. browser, Node.js)
- Pick and choose background system that make sense for you
Users define qubits object like below.
const qubit1 = new Qubit();
const qubit2 = new Qubit();
qubit1.x();
Variable qubit1 mean 1 logical qubit, has a quantum gate method. Then, users can apply arbitrary gates on each qubits independently.
Multi-qubit gate requires Qubit as an argument. After applying the multi-qubit gate, individual qubit variables are still available. Users don't have to consider how qubit1 and qubit2 are entangled.
const qubit1 = new Qubit();
const qubit2 = new Qubit();
qubit1.h();
qubit2.cnot(qubit1); // generate synthetic quantum system
qubit2.x(); // keep independent qubit interface
You can see qubit interface reference here.
qramana is JavaScript module written in TypeScript, published to npm.
Also, qramana doesn't depend on browser/Node.js specific features.
Therefore, users can develop with TypeScript and use qramana in any Javascript implementation.
qramana can choose some backend system.
If you want to add new backend systems, you can use it by implementing driver.
qramana-common-types is
Type definition for driver interface.
Default driver implementation is here.
Currently, qramana uses jsqubits for its backend.
