When quantum state tomography benefits from willful ignorance
نویسندگان
چکیده
We show that quantum state tomography with perfect knowledge of the measurement apparatus proves to be, in some instances, inferior strategies discarding all information about at hand, as case data pattern tomography. In those scenarios, larger uncertainty is traded for smaller reconstructed signal. This effect more pronounced minimal or nearly informationally complete settings, which are utmost practical importance.

Willful Ignorance in a World of Biased Misinformation
Suppose individuals face a claim of uncertain validity and can only obtain more information from sources known to sometimes report biased misinformation for or against the claim. In such an environment, it is optimal for Bayesian expected utility maximizers to select the source biased toward their current behavior even if they know that source more frequently reports misinformation than an oppo...
متن کاملDoes Willful Ignorance Deflect Punishment? – An Experimental Study
This paper studies whether people can avoid punishment by remaining willfully ignorant about possible negative consequences of their actions for others. We employ a laboratory experiment, using modified dictator games in which a dictator can remain willfully ignorant about the payoff consequences of his decision for a receiver. A third party can punish the dictator after observing the dictator’...
متن کاملEfficient quantum state tomography.
Quantum state tomography--deducing quantum states from measured data--is the gold standard for verification and benchmarking of quantum devices. It has been realized in systems with few components, but for larger systems it becomes unfeasible because the number of measurements and the amount of computation required to process them grows exponentially in the system size. Here, we present two tom...
متن کاملReliable quantum state tomography.
Quantum state tomography is the task of inferring the state of a quantum system by appropriate measurements. Since the frequency distributions of the outcomes of any finite number of measurements will generally deviate from their asymptotic limits, the estimates computed by standard methods do not in general coincide with the true state and, therefore, have no operational significance unless th...
متن کاملWhen Ignorance is Bliss
It is commonly-accepted wisdom that more information is better, and that information should never be ignored. Here we argue, using both a Bayesian and a non-Bayesian analysis, that in some situations you are better off ignoring information if your uncertainty is represented by a set of probability measures. These include situations in which the information is relevant for the prediction task at...
