Inaccurate (weak) measurements classical and quantum
D. Sokolovski, D. Alonso, S. Brouard
We consider highly inaccurate measurements made on classical stochastic and quantum systems. In the quantum case such a \e{weak} measurement preserves coherence between the system'…
Quantum reflection time and the Goos-Hänchen effect
D. Sokolovski, A. Uranga, Y. Caudano
We explore the analogy between following the motion of a reflected wave packet, and a quantum measurement of the spatial delay imposed on the particle by the scattering potential.…
Quantum weak values and the 'which way?' question
A. Uranga, E. Akhmatskaya, D. Sokolovski
Uncertainty principle forbids one to determine which of the two paths a quantum system has travelled, unless interference between the alternatives had been destroyed by a measuring…
Speakable and unspeakable in quantum measurements
D. Sokolovski, D. Alonso, S. Brouard
Quantum mechanics, in its orthodox version, imposes severe limits on what can be known, or even said, about the condition of a quantum system between two observations. A relatively…
