Quantum Data Integrity Verification Methods
Methods for verifying data integrity with quantum techniques, how they compare with classical checks and where they could be used.
Quantum Anonymous Transfer and Untraceable Messages
Quantum anonymous transmission hides who sent a message and to whom using shared entanglement. How the protocols work and their limits.
Multi-Party Computation With Quantum Resources
Quantum multi-party computation lets several parties compute jointly on private data using quantum resources. Protocols, security and scaling.
Quantum Coin Tossing Protocols and Their Bias
Quantum coin tossing protocols and their bias bounds: why perfect strong coin flipping is impossible and what weak protocols achieve.
Quantum Secret Splitting Across Several Holders
Quantum secret splitting divides a secret among several holders using quantum states so no single holder can read it. How it works in practice.
Quantum Position Verification: Proving Where You Are
Quantum position verification tries to prove a party’s location using quantum signals. Why no-go results limit it and what still works.
Quantum Identification Protocols, Explained
Quantum identification protocols verify identity using quantum states and keys. Entanglement-based schemes, QKD systems and security.
Elliptic Curve Cryptography Against Quantum Attack
Why Shor’s algorithm breaks elliptic curve cryptography, how many qubits that would take and which post-quantum schemes replace ECC.
Quantum Group Signatures and Anonymity
Quantum group signatures let a member sign for a group anonymously while a manager can trace abuse. How they work and their security.
Quantum Information Splitting Between Parties
Quantum information splitting distributes a quantum state among parties so that they must cooperate to recover it. Protocols and uses.
