Gain on ground state of quantum system for truly $P T$ symmetry

Bing-Bing Liu, Shi-Lei Su

For a truly $P T$ -symmetric quantum system, the conventional non-Hermitian Hamiltonian is $H = I^c ◯ I ¨ _{x} - i I^^{3} ∣1 ⟩ ⟨ 1∣ + i I^^{3} ∣0 ⟩ ⟨ 0∣$ , where $I^c ◯$ and $I^^{3}$ …

Using PT-symmetric Qubits to Break the Tradeoff Between Fidelity and the Degree of Quantum Entanglement

B. -B. Liu, Shi-Lei Su, Y. -L. Zuo +4

A noteworthy discovery is that the minimal evolution time is smaller for parity-time ( $P T$ ) symmetric systems compared to Hermitian setups. Moreover, there is a significa…
