abstract
We propose various new techniques in quantum information theory, including a de Finetti style representation theorem for finite symmetric quantum states. As an application, we give a proof for the security of quantum key distribution which applies to arbitrary protocols.

The authors prove a no-go result on tightening the Dupuis et al. chain rule in the device-independent setting and introduce a new chain rule that slightly improves the Rényi EAT in certain contexts, while unifying existing chain rules.
A general conic optimization solver computes finite-size QKD rates from Rényi entropies more reliably than prior Frank-Wolfe methods.
Proves additivity of doubly minimized Petz Renyi mutual information for alpha in [1/2,2] and a novel duality plus additivity for the sandwiched version for alpha in [2/3, infinity] via Sion's minimax theorem.
Presents a single-photon DI-QKD scheme and self-testing QRNG whose security rests on no-signaling polytope decomposition and a Clauser-Horne inequality involving on/off weak homodyne settings.
Robustness theorems establish that asymptotic entanglement manipulation rates for MSR almost i.i.d. sources equal those of their i.i.d. references, with universal protocols for pure states.
Establishes noncommutative weak law of large numbers and universal entropy concentration for weakly almost i.i.d. quantum sources.
Robust protocols are identified for three quantum Shannon tasks under three notions of almost i.i.d. structure that preserve i.i.d. rates, along with new concepts of almost i.i.d. process and club distance.
The generalized quantum Stein's lemma remains valid for almost-iid states via a new continuity bound on relative entropy of entanglement with respect to quantum Wasserstein distance.
The direct exponent in binary quantum state discrimination for correlation detection equals the doubly minimized Petz Renyi mutual information for alpha in (1/2,1), while the strong converse exponent equals the doubly minimized sandwiched version for alpha in (1,infty).
Quantum Markov semigroups on d-dimensional systems have infinite-time capacities determined by peripheral space structure, with convergence after time t ≳ d² ln(d), and explicit bounds showing n-qubit memories fail after t ≳ n 2^{2n} (global correction) or t ≳ ln(n) (local).
Hybrid entangled PUFs generate an ITS initial authentication key, allowing a complete entanglement-based QKD protocol without pre-shared secrets under minimal hardware assumptions.
