Random access test as an identifier of nonclassicality

Teiko Heinosaari, Leevi Leppäjärvi

Random access codes are an intriguing class of communication tasks that reveal an operational and quantitative difference between classical and quantum information processing. We f…

Non-Markovian Quantum Dynamics in Strongly Coupled Multimode Cavities Conditioned on Continuous Measurement

Valentin Link, Kai Müller, Rosaria G. Lena +4

An important challenge in non-Markovian open quantum systems is to understand what information we gain from continuous measurement of an output field. For example, atoms in multimo…

Incompatible measurements in quantum information science

Otfried Gühne, Erkka Haapasalo, Tristan Kraft +2

Some measurements in quantum mechanics disturb each other. This has puzzled physicists since the formulation of the theory, but only in recent decades has the incompatibility of me…

Joint measurability in nonequilibrium quantum thermodynamics

Konstantin Beyer, Roope Uola, Kimmo Luoma +1

In this Letter we investigate the concept of quantum work and its measurability from the viewpoint of quantum measurement theory. Very often, quantum work and fluctuation theorems…

Experimental Snapshot Verification of non-Markovianity with Unknown System-Probe Coupling

Henri Lyyra, Olli Siltanen, Jyrki Piilo +2

We apply the recently proposed quantum probing protocols with an unknown system-probe coupling to probe the convex coefficients in mixtures of commuting states. By using two refere…

Open quantum dynamics with singularities: Master equations and degree of non-Markovianity

Abhaya S. Hegde, K. P. Athulya, Vijay Pathak +2

Master equations describing open quantum dynamics are typically first order differential equations. When such dynamics brings the trajectories in state space of more than one initi…

Engineering of Hong-Ou-Mandel interference with effective noise

Olli Siltanen, Tom Kuusela, Jyrki Piilo

The Hong-Ou-Mandel effect lies at the heart of quantum interferometry, having multiple applications in the field of quantum information processing and no classical counterpart. Des…

Testing incompatibility of quantum devices with few states

Teiko Heinosaari, Takayuki Miyadera, Ryo Takakura

When observations must come from incompatible devices and cannot be produced by compatible devices? This question motivates two integer valued quantifications of incompatibility, c…

Contextuality and dichotomizations of random variables

Janne V. Kujala, Ehtibar N. Dzhafarov

The Contextuality-by-Default approach to determining and measuring the (non)contextuality of a system of random variables requires that every random variable in the system be repre…

Quantum speed limit and divisibility of the dynamical map

Jose Teittinen, Sabrina Maniscalco

The quantum speed limit (QSL) is the theoretical lower limit of the time for a quantum system to evolve from a given state to another one. Interestingly, it has been shown that non…
