TRACE: Temporal Risk Assessment and Concept Editing for Safer Language Generation
Ankur Garg, Xuemin Yu, Hassan Sajjad +1
Large language models (LLMs) can produce harmful content while generating a response. A useful safeguard should not only detect this risk during generation but also intervene while…
Ordering controlled by the measurement-feedback interval in quantum Boltzmann samplers
Peng Wang, Yu-Xuan Zhang, Hai-Tao Ding +1
We show that the measurement--feedback interval alone can induce ordering in a quantum Boltzmann sampler with fixed programmed couplings and a fixed local dissipative rule. At zero…
Classical Bound on the Fisher Information Rate of a Dephasing-Enhanced Quantum Neuron
Peng Wang, Yu-Xuan Zhang, Hai-Tao Ding +1
Dephasing can sharpen the activation of a dissipative quantum neuron, but a stationary response does not determine how much input information its output delivers per unit time. For…
Quantum geometric bounds at finite temperature for one-dimensional chiral systems
Peng He, Hai-Tao Ding, Yu-Guo Liu
The geometry and topology of quantum states are intimately related at zero temperature through exact bounds that constrain geometric quantities from below by topological invariants…
The Geometric Phase as a Diagnostic for Driven-Dissipative Oscillators
Zeen Sun, Yuan Shen, Haitao Ding +2
Driven-dissipative quantum oscillators lock their phase, deform their limit cycles, and undergo dissipative phase transitions, yet these behaviors are read from unrelated quantitie…
Manipulation of Topological Corner States via Subchiral Symmetry
Hai-Tao Ding, Tianqi Chen, Leong-Chuan Kwek +1
Higher-order topological phases provide robust corner modes, but their use requires controllable creation, isolation, and transfer of individual modes and their superpositions. Her…
Enhanced Density Fluctuations Near a Disordered Chiral Topological Transition
Hai-Tao Ding, Sen Mu, Leong-Chuan Kwek +2
The universal statistics of density fluctuations of localized quantum states may offer unprecedented opportunities to probe and understand quantum transport in connection with dime…
Floquet quantum geometry in periodically driven topological insulators
Peng He, Jian-Te Wang, Jiangbin Gong +1
Quantum geometry plays a fundamental role across many branches of modern physics, yet its full characterization in nonequilibrium systems remains a challenge. Here, we propose a fr…
