Generalized measurement incompatibility
Edwin Peter Lobo, Maria Balanzó-Juandó, Stefano Pironio
Quantum measurements can be incompatible, i.e., they can fail to be jointly measurable. Recently, a weaker notion of joint-measurability, called partial joint-measurability, was pr…
All pure entangled states can lead to fully nonlocal correlations
Martin J. Renner, Edwin Peter Lobo, Arturo Konderak +2
It is a well-established fact that some quantum correlations can be nonlocal, meaning that they cannot be described by a local hidden variable model. Certain quantum correlations h…
Certification of quantum correlations and DIQKD at arbitrary distances through routed Bell tests
Pavel Sekatski, Jef Pauwels, Edwin Peter Lobo +2
Transmission loss represents a major obstacle to the device-independent certification of quantum correlations over long distances, limiting applications such as device-independent…
Device-Independent Quantum Key Distribution Based on Routed Bell Tests
Tristan Le Roy-Deloison, Edwin Peter Lobo, Jef Pauwels +1
Photon losses are the main obstacle to fully photonic implementations of device-independent quantum key distribution (DIQKD). Motivated by recent work showing that routed Bell scen…
Quantum Advantage: A Single Qubit's Experimental Edge in Classical Data Storage
Chen Ding, Edwin Peter Lobo, Mir Alimuddin +5
We implement an experiment on a photonic quantum processor establishing efficacy of the elementary quantum system in classical information storage. The advantage is established by…
Certifying long-range quantum correlations through routed Bell tests
Edwin Peter Lobo, Jef Pauwels, Stefano Pironio
Losses in the transmission channel, which increase with distance, pose a major obstacle to photonics demonstrations of quantum nonlocality and its applications. Recently, Chaturved…
Overcoming Traditional No-Go Theorems: Quantum Advantage in Multiple Access Channels
Ananya Chakraborty, Sahil Gopalkrishna Naik, Edwin Peter Lobo +5
Extension of point-to-point communication model to the realm of multi-node configurations finds a plethora of applications in internet and telecommunication networks. Here, we esta…
Timelike correlations and quantum tensor product structure
Samrat Sen, Edwin Peter Lobo, Ram Krishna Patra +4
The state space structure for a composite quantum system is postulated among several mathematically consistent possibilities that are compatible with local quantum description. For…
Principle of information causality rationalizes quantum composition
Ram Krishna Patra, Sahil Gopalkrishna Naik, Edwin Peter Lobo +4
Principle of information causality, proposed as a generalization of no signaling principle, has efficiently been applied to outcast beyond quantum correlations as unphysical. In th…
Classical analogue of quantum superdense coding and communication advantage of a single quantum system
Ram Krishna Patra, Sahil Gopalkrishna Naik, Edwin Peter Lobo +5
We analyze utility of communication channels in absence of any short of quantum or classical correlation shared between the sender and the receiver. To this aim, we propose a class…
Certifying beyond quantumness of locally quantum no-signalling theories through quantum input Bell test
Edwin Peter Lobo, Sahil Gopalkrishna Naik, Samrat Sen +3
Physical theories constrained with local quantum structure and satisfying the no-signalling principle can allow beyond-quantum global states. In a standard Bell experiment, correla…
Local Quantum State Marking
Samrat Sen, Edwin Peter Lobo, Sahil Gopalkrishna Naik +8
We propose the task of local state marking (LSM), where some multipartite quantum states chosen randomly from a known set of states are distributed among spatially separated partie…
Composition of multipartite quantum systems: perspective from time-like paradigm
Sahil Gopalkrishna Naik, Edwin Peter Lobo, Samrat Sen +5
Figuring out the physical rationale behind natural selection of quantum theory is one of the most acclaimed quests in quantum foundational research. This pursuit has inspired sever…
