QUBO Modeling of Module Learning With Errors: Stability and Scaling in Post-Quantum Cryptography
Ruturaj Khamitkar, Durga Pritam Suggisetti, Soujanya Chatti +2
Lattice-based post-quantum cryptography relies on the hardness of the Learning With Errors (LWE) and Module Learning With Errors (MLWE) problems. This work introduces a constructiv…
Steady-state entanglement of spin qubits mediated by nonreciprocal and chiral magnons
Martijn Dols, Mikhail Cherkasskii, Victor A. S. V. Bittencourt +3
We propose a hybrid quantum system in which a magnet supporting non-reciprocal magnons, chiral magnons, or both mediates the dissipative and unidirectional coupling of spin qubits.…
Strain-induced modification of spin-optical dynamics in silicon vacancy centers for integrated quantum technologies
Maximilian Hollendonner, Fedor Dzmitryevich Hrunski, Daniel Scheller +8
Silicon vacancy (VSi) centers in 4H silicon carbide have emerged as a highly promising platform for semiconductor-based quantum technologies, combining excellent spin and optical p…
Enhanced security in Quantum Token protocols using Hybrid Spin-Photon Interfaces
Durga Bhaktavatsala Rao Dasari, Yang Wang, Jörg Wrachtrup
Quantum token protocols enable unforgeable quantum tokens promising unconditional security beyond classical cryptographic assumptions. We show here that the three stages of the Qua…
Collective purification of interacting quantum networks beyond symmetry constraints
Saikat Sur, Pritam Chattopadhyay, Arnab Chakrabarti +5
Following any quantum information processing protocol, it is essential to reset a mixed state of a many-body interacting spin-network to the computational-zero pure state. This tas…
Near-limit quantum control beyond analytic tractability in many-body spin systems
Jixing Zhang, Bo Peng, Yang Wang +11
As quantum control approaches hardware-imposed performance limits, weak effects omitted by reduced models become consequential. Assumptions required for analytic tractability then…
