Postponing the choice: advantage of deferred measurements in quantum information processing
C. Carmeli, T. Heinosaari, A. Toigo
Simultaneously implementing two arbitrary quantum measurements on the same system is impossible. The consequence of this limitation is that selecting one measurement actively exclu…
Anticipative measurements in hybrid quantum-classical computation
Teiko Heinosaari, Daniel Reitzner, Alessandro Toigo
Before the availability of large scale fault-tolerant quantum devices, one has to find ways to make the most of current noisy intermediate-scale quantum devices. One possibility is…
Experimentally determining the incompatibility of two qubit measurements
Andrea Smirne, Simone Cialdi, Daniele Cipriani +3
We describe and realize an experimental procedure for assessing the incompatibility of two qubit measurements. The experiment consists in a state discrimination task where either m…
Quantum guessing games with posterior information
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
Quantum guessing games form a versatile framework for studying different tasks of information processing. A quantum guessing game with posterior information uses quantum systems to…
Quantum random access codes and incompatibility of measurements
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
We prove that quantum random access code (QRAC) performs better than its classical counterpart only when incompatible quantum measurements are used in the decoding task. As a conse…
Witnessing incompatibility of quantum channels
Claudio Carmeli, Teiko Heinosaari, Takayuki Miyadera +1
We introduce the notion of incompatibility witness for quantum channels, defined as an affine functional that is non-negative on all pairs of compatible channels and strictly negat…
