Bell state entropy computed as $1$ bit from the reduced density matrix.
CHSH expectation value $2.8284$ verified violation of Bell inequalities.
Schmidt decomposition of a random state yielded coefficients $(0.944, 0.329)$.
Teleportation simulations of 100 random qubits achieved mean fidelity $F\approx1$, demonstrating a correct implementation of the Bennett protocol.
Tracing out two qubits of a GHZ state produced a maximally mixed single-qubit density matrix with entropy $1$ bit.
Entanglement swapping from two Bell pairs produced an output Bell state with concurrence near unity.
The Bell state violated the CHSH inequality with $\langle B\rangle=2\sqrt2$, matching the Tsirelson bound.
Tracing the $W$ state down to one qubit produced an entropy of $0.918$ bits.
A mixed state's partial transpose yielded a negativity of $0.12$.
A $2\times2$ mixed state exhibited entropy $0.72$ bits.
Teleportation under $10\%$ depolarising noise retained fidelity $0.93$.
Sampling five random states gave mean concurrence about $0.5$.
