Quantum Computing is an app by hex@dec in the Education category, listed since at least December 2021. It has no native code, so it runs on any Android processor.
What's new in v0.19.3–210731
0.19.3:
- Fixed an extremely rare bug that caused the app to crash
0.19.1 & 0.19.2:
- Fixed a bug that crashed the app when the screen was rotated
- UX improvements
- Save the statevector so that the second run will be a lot faster
- Gate editor fixes
Description
From the listing uploaded by “appupdater”.
A software for Android that emulates the actions of a quantum computer
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!
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.
The application uses a home-made backend for simulating quantum circuits. It does not
work with noise. The backend is written in Java and the entire source code can be found on GitHub at
Please be aware that the qubit order in this application is
, 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
, thus most multi-qubit gate matrices need conversion!

Quantum Computing APK: questions and answers
Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.
Is the Quantum Computing APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 0c162f6208d740ba245289f717b2848e.
