Pure 3-qubit states

3-Qubit-State SLOCC & SD Calculator

This classifier partitions pure states of three qubits into six SLOCC classes: GHZ, W, A-BC, B-AC, C-AB, and A-B-C.

Also calculates the Schmidt decomposition (SD) of the three qubit state.

Reference for SD of three qubits: A. Acin et al., Phys. Rev. Lett. 85, 1560 (2000)

Enter the 8 complex numbers for your 3-qubit-state in the boxes below.
Operations: + - * / ^ sqrt sin cos tan, "i" = √-1, "pi" = 3.1415...

SD is of the following form: r₀|000>+r₁e^ix|100> +r₂|101>+r₃|110>+r₄|111>
Program will output [r₀, r₁e^ix, r₂, r₃, r₄]

c₀ -> c₇ default to 0 if left blank

Arbitrary n-qubit states

n-Qubit-State Entanglement Detector

Using a sufficient and necessary condition, this classifier can detect both entangled and separable states.

Operations: + - * / ^ sqrt sin cos tan, "i" = √-1, "pi" = 3.1415...
Trig functions use radians.

Only input non-zero constants for your state, omitted constants default to 0
