Colbeck [Ph.D. thesis, 2006] proposed using Bell inequality violations to generate certified random numbers. While full quantum-security proofs have been given, it remains a major open problem to identify the broadest class of Bell inequalities and lowest performance requirements to achieve such security. In this paper, working within the broad class of spot-checking protocols, we prove exactly which Bell inequality violations can be used to achieve full security. Our result greatly improves…

An adaptive framework for quantum-secure device-independent randomness expansion
TLDR
A protocol that robustly generates up to two bits of randomness per entangled qubit pair, which is twice that established in existing analyses of the spot-checking CHSH protocol in the low noise regime.
Simple and tight device-independent security proofs
TLDR
A flexible protocol is provided and a security proof is given that provides quantitative bounds that are asymptotically tight, even in the presence of general quantum adversaries, which is likely that these protocols can be practically implemented in the near future.
A Framework for Quantum-Secure Device-Independent Randomness Expansion
TLDR
A protocol that robustly generates up to two bits of randomness per entangled qubit pair, which is twice that established in existing analyses of the spot-checking CHSH protocol in the low noise regime.
Efficient Randomness Certification by Quantum Probability Estimation.
TLDR
This work implements quantum probability estimation for device-independent randomness generation in the CHSH Bell-test configuration, and it shows significant improvements in finite-data efficiency, particularly at small Bell violations which are typical in current photonic loophole-free Bell tests.
Randomness Expansion Secured by Quantum Contextuality
TLDR
A modified Klyachko-Can-Binicioglu-Shumovsky contextuality inequality is employed, which can ease the strict compatibility requirement on measurements for sequential measurements in contextuality tests and paves the way for the practical high-speed spot-checking quantum random number expansion and other secure information processing applications.
Experimentally generated randomness certified by the impossibility of superluminal signals
TLDR
1,024 random bits that are uniformly distributed to within 10−12 and unpredictable assuming the impossibility of superluminal communication are generated and certified using a loophole-free Bell test and a protocol is described that is optimized for devices that are characterized by a low per-trial violation of Bell inequalities.
Improved device-independent randomness expansion rates from tight bounds on the two sided randomness using CHSH tests
TLDR
The minimum von Neumann entropies for a given CHSH score are found and the gain that can be made by using the two-sided randomness and by using a protocol without spot-checking where the input randomness is recycled.
Calculation and application of various von Neumann entropies in CHSH-based device-independent randomness expansion
TLDR
The minimum von Neumann entropies for a given CHSH score are found and the gain that can be made by using the two-sided randomness and by using a protocol without spot-checking where the input randomness is recycled.
On Bit Commitment and Oblivious Transfer in Measurement-Device Independent settings
TLDR
This paper proposes for the first time protocols for Bit Commitment and Oblivious Transfer in the measurement-device independent (MDI) settings and analyzes their security, showing that there is a whole class of protocols that cannot be secure.
An Elementary Proof of Private Random Number Generation from Bell Inequalities
TLDR
A short proof that any bipartite Bell violation can be used to generate private random numbers and is based on elementary techniques and is self-contained.

Robust protocols for securely expanding randomness and distributing keys using untrusted quantum devices
TLDR
This work shows how to expand a random seed at an exponential rate without trusting the underlying quantum devices, and has the following new features: tolerating a constant level of implementation imprecision, requiring only a unit size quantum memory per device component for the honest implementation, and allowing a large natural class of constructions.
Security and Composability of Randomness Expansion from Bell Inequalities
TLDR
A meaningful lower bound on the min-entropy of the data produced by an untrusted device based on the observed nonlocal behavior of the device is obtained and confirms the essence of the (improperly formulated) claims of Pironio et al. and puts them on solid ground.
Physical Randomness Extractors: Generating Random Numbers with Minimal Assumptions
TLDR
The Equivalence Lemma, a general principle for proving composition security of untrusted-device protocols, implies that unbounded randomness expansion can be achieved simply by cross-feeding any two expansion protocols, and can be made robust, which is known for the first time.
Security of practical private randomness generation
TLDR
It is pointed out that in most real, practical situations, where the concept of device independence is used as a protection against unintentional flaws or failures of the quantum apparatuses, it is sufficient to show that the generated string is random with respect to an adversary that holds only classical side information; i.e., proving randomness against quantum side information is not necessary.
Bounding the seed length of Miller and Shi's unbounded randomness expansion protocol
TLDR
An analysis of the required seed size is presented, giving explicit upper bounds for the number of initial random bits needed to jump-start the protocol.
Contextuality offers device-independent security
TLDR
This work shows that if two persons share systems which locally exhibit the Kochen-Specker paradox, then they can extract secure key, even if they do not trust the quantum devices, which is the first operational protocol that directly implements the fundamental feature of Nature: the information gain vs. disturbance trade-off.
Certifiable quantum dice: or, true random number generation secure against quantum adversaries
TLDR
A modified protocol uses a seed of O(log3 n) uniformly random bits to generate n bits that are poly-1(n)-indistinguishable from uniform even from the point of view of a quantum adversary who may have had prior access to the devices, and may be entangled with them.
Quantum-Proof Randomness Extractors via Operator Space Theory
TLDR
It is argued that the theory of operator spaces offers a natural framework for studying to what extent extractors are secure against quantum adversaries: it is shown that very high min-entropy extractors as well as extractors with small output are always (approximately) quantum-proof.
Multi-Source Randomness Extractors Against Quantum Side Information, and their Applications
TLDR
A new model called General Entangled (GE) Adversary Model, which allows arbitrary entanglement in the side information and subsumes both the IA model and the BS model is proposed, and equivalence between strong OA-security and strong GE-security is established.
Optimal robust quantum self-testing by binary nonlocal XOR games
Self-testing a quantum device means verifying the existence of a certain quantum state as well as the effect of the associated measurements based only on the statistics of the measurement outcomes.
