Quantum Computing

Developer's DescriptionBy hex@decA software for Android that emulates the actions of a quantum computer...A software for Android that emulates the actions of a quantum computeressentially a quantum computer simulator with limited functionalityIt'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 backendThe 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/QuantumPlease 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 featuresAt most 10 qubitsGates with at most 4 qubitsExtremely high number of shots (up to 2^20)Lots of predefined gatesGet results immediatelyExport resultsImport/Export gate sequence, export as OpenQASMTake the hermitian conjugate of any gateShow bloch sphere (for non-entagled qubits)Show the statevector of the systemAuto and Opt-in circuit optimizationPredefined single qubit gatesHadamardPauli-X/Y/ZS-gate & T-gate (phase-shift)NOTIdentityU3Predefined multi qubit gatesCNOT/CY/CZ (Controlled-Pauli)Controlled-S, Controlled-T and Controlled-Hadamard gatesSWAPToffoliFredkinPlanned featuresCreate and run algorithms with loops and conditionsTranslators are welcomed at the GitHub repository:https://github.com/hexadec/Quantum/blob/master/app/src/main/res/values/strings.xml
