Quantum Algorithms for Lattice Problems
Quantum algorithms for lattice problems and quantum lattice models, and why lattice-based cryptography is believed to resist quantum attacks.
Quantum Correlation Complexity and Its Measures
Measures of quantum correlations beyond entanglement, such as discord, how they differ from classical correlations and where they matter.
Quantum Coherence as a Resource, Quantified
The resource theory of coherence treats superposition as a resource that can be measured. Coherence measures and their link to entanglement.
Entanglement Complexity: Measuring How Tangled
How entanglement is quantified: entanglement entropy, witnesses and other measures, plus experiments, swapping, teleportation and networks.
Quantum Threshold Logic and Its Circuits
Threshold logic gates fire when a weighted sum passes a threshold. How this idea is carried over to quantum circuits and where it might apply.
Quantum Sparse Coding and Dictionary Learning
Quantum approaches to sparse coding and dictionary learning: how data might be encoded in quantum states and how they compare with classical ones.
How Hard Are Quantum Neural Networks to Train?
Why quantum neural networks can be hard to train: barren plateaus, circuit depth, qubit connectivity, noise and the complexity trade-offs.
Quantum Boltzmann Machines and Their Training
Quantum Boltzmann machines extend Boltzmann machines with quantum terms. How they are trained, possible uses and current challenges.
The Cost of Quantum State Tomography
Full quantum state tomography needs a number of measurements that grows exponentially with qubits. The cost, the methods and the alternatives.
The BB84 Protocol: The First QKD Scheme
BB84, proposed by Bennett and Brassard in 1984, was the first QKD protocol. How it encodes bits in photons and detects eavesdropping.
Quantum Computational Geometry and Its Algorithms
Quantum algorithms for computational geometry problems such as convex hulls and point location, and where speedups are possible.
