Title: Engineering two-qubit mixed states with weak measurements
Authors: Parveen Kumar, Kyrylo Snizhko, and Yuval Gefen
Abstract summary: It is known that protocols based on weak measurements can be used to steer quantum systems into pre-designated pure states. Here we show that weak-measurement-based steering protocols can be harnessed for on-demand engineering of $textitmixed$ states.

Abstract: It is known that protocols based on weak measurements can be used to steer quantum systems into pre-designated pure states. Here we show that weak-measurement-based steering protocols can be harnessed for on-demand engineering of $\textit{mixed}$ states. In particular, through a continuous variation of the protocol parameters, one can guide a classical target state to a discorded one, and further on, towards an entangled target state.

Certifying classes of $d$-outcome measurements with quantum steering [49.1574468325115]
We provide a construction of a family of steering inequalities tailored to large classes of $d$-outcomes projective measurements. We prove that the maximal quantum violation of those inequalities can be used for certification of those measurements and the maximally entangled state of two qudits.

Orthogonal-state-based Measurement Device Independent Quantum Communication [32.244698777387995]
We propose a new protocol of measurement-device-independent quantum secure direct communication and quantum dialogue employing single basis, i.e., Bell basis as decoy qubits for eavesdropping detection. Our protocols leverage fundamentally distinct resources to close the security loopholes linked to measurement devices, while also effectively doubling the distance for secure direct message transmission.

Dilute measurement-induced cooling into many-body ground states [0.5492530316344587]
Cooling a quantum system to its ground state is important for the characterization of non-trivial interacting systems. We identify conditions under which measurement-based cooling protocols can be taken to the dilute limit. For two examples of frustration-free one-dimensional spin chains, we show that steering on a single link is sufficient to cool these systems into their unique ground states.

Engineering unsteerable quantum states with active feedback [0.5892638927736115]
We propose active steering protocols for quantum state preparation in quantum circuits. We show that the standard fidelity does not give a useful cost function; instead, successful steering is achieved by including local fidelity terms. numerical simulations suggest that the active steering protocol can reach arbitrarily designated target states.

Robust and efficient verification of graph states in blind measurement-based quantum computation [52.70359447203418]
Blind quantum computation (BQC) is a secure quantum computation method that protects the privacy of clients. It is crucial to verify whether the resource graph states are accurately prepared in the adversarial scenario. Here, we propose a robust and efficient protocol for verifying arbitrary graph states with any prime local dimension.

Reliable Quantum Communications based on Asymmetry in Distillation and Coding [35.693513369212646]
We address the problem of reliable provision of entangled qubits in quantum computing schemes. We combine indirect transmission based on teleportation and distillation; (2) direct transmission, based on quantum error correction (QEC) Our results show that ad-hoc asymmetric codes give, compared to conventional QEC, a performance boost and codeword size reduction both in a single link and in a quantum network scenario.
