Impossibility of Quantum Bit Commitment, a Categorical Perspective [PDF]
Axioms, 2020 Bit commitment is a cryptographic task in which Alice commits a bit to Bob such that she cannot change the value of the bit after her commitment and Bob cannot learn the value of the bit before Alice opens her commitment. According to the Mayers−Lo&

An Information-Theoretic Perspective on the Quantum Bit Commitment Impossibility Theorem [PDF]
Entropy, 2018 This paper proposes a different approach to pinpoint the causes for which an unconditionally secure quantum bit commitment protocol cannot be realized, beyond the technical details on which the proof of Mayers’ no-go theorem is constructed.

On the Efficiency of Bit Commitment Reductions [PDF]
Lecture Notes in Computer Science, 2011 Two fundamental building blocks of secure two-party computation are oblivious transfer and bit commitment. While there exist unconditionally secure implementations of oblivious transfer from noisy correlations or channels that achieve constant rates, similar constructions are not known for bit commitment.

A practical quantum bit commitment protocol [PDF]
Results in Physics, 2012 In this paper, we introduce a new quantum bit commitment protocol which is practically secure against entanglement attacks. A general cheating strategy is discussed and shown to be practically ineffective against the proposed approach.

Practical Quantum Bit Commitment Protocol Based on Quantum Oblivious Transfer [PDF]
Applied Sciences, 2018 Oblivious transfer (OT) and bit commitment (BC) are two-party cryptographic protocols which play crucial roles in the construction of various cryptographic protocols. We propose three practical quantum cryptographic protocols in this paper.

A Private Quantum Bit String Commitment [PDF]
Entropy, 2020 We propose an entanglement-based quantum bit string commitment protocol whose composability is proven in the random oracle model. This protocol has the additional property of preserving the privacy of the committed message.

Summoning, No-Signalling and Relativistic Bit Commitments
Entropy, 2019 Summoning is a task between two parties, Alice and Bob, with distributed networks of agents in space-time. Bob gives Alice a random quantum state, known to him but not her, at some point. She is required to return the state at some later point, belonging

Commitment Schemes from OWFs with Applications to Quantum Oblivious Transfer [PDF]
EntropyCommitment schemes (CSs) are essential to many cryptographic protocols and schemes with applications that include privacy-preserving computation on data, privacy-preserving authentication, and, in particular, oblivious transfer protocols.

Semi-Counterfactual Quantum Bit Commitment Protocol. [PDF]
Sci Rep, 2020 AbstractA semi-counterfactual quantum bit commitment (SCQBC) protocol is presented here for the first time, which makes use of counterfactual property. Similar to a counterfactual quantum key distribution scheme, half-photons are not transmitted through the quantum channel in our proposed protocol.
