A software for Android that emulates the actions of a quantum computer
essentially a quantum computer simulator with limited functionality

It's main purpose is to enable testing to everyone even on the go. Since this app is only an emulator it can show the position of the qubits on the bloch sphere. This app can also show the statevector of the system (in probability mode) and the final unitary gate will also be accessible soon. The limit is only the computing power of your device!

Help testing and join the beta program for new functionality!

You can apply any matrices to your qubits as long as they are member of the group SU(n) – they have to be unitary and have to have a unit determinant.

About the backend
The application uses a home-made backend for simulating quantum circuits. It does not yet work with noise. The backend is written in Java and the entire source code can be found on GitHub at hexadec/Quantum
Please be aware that the qubit order in this application is Big-Endian meaning that in a multi-qubit gate always the first parameter is the last bit in the statevector whereas some other well-known system are Little-Endian thus most multi-qubit gate matrices need conversion!

Main features

• Take the hermitian conjugate of any gate
• Show bloch sphere (for non-entangled qubits)
• Show the statevector of the system
• Auto and Opt-in circuit optimization

Predefined single qubit gates
• Hadamard
• Pauli-X/Y/Z
• S-gate & T-gate (phase-shift)

About this version (0.18.7–201228)

Quantum Computing is back to make your 2020 a bit brighter! Here are some of the changes I find important in version 0.18.7: - Added controlled U3-gate - Removed Rotation gate - Some performance improvements and bugfixes - Hopefully fixed a multi-qubit gate bug - You can choose not to measure some gates by clicking on their names - Layout won't collapse now, when you use multi-qubit gates (expect better looking circuits)
