The ability to post-select the outcomes of an experiment is a useful theoretical concept and experimental tool. In the context of weak measurements, post-selection can lead to surprising results such as complex weak values outside the range of eigenvalues. Usually post-selection is realized by a projective measurement, which is hard to implement in ensemble systems such as NMR. We demonstrate the first experiment of a weak measurement with post-selection on an NMR quantum information processor…

Quantum computing exploits fundamentally new models of computation based on quantum mechanical properties instead of classical physics, and it is believed that quantum computers are able to
A scheme for performing strong and weak sequential measurements of non-commuting observables
Quantum systems usually travel a multitude of different paths when evolving through time from an initial to a final state. In general, the possible paths will depend on the future and past boundary
Tomography is Necessary for Universal Entanglement Detection with Single-Copy Observables.
TLDR
A no-go theorem is proved that rules out the possibility of universal entanglement detection of two-qubit states via adaptive single-copy measurements without full state tomography for nonadaptive schemes that employ single- copy measurements only.
Scheme and experimental demonstration of fully atomic weak-value amplification
In this Letter, we experimentally demonstrate the first realization of weak value amplification (WVA) using purely atomic degrees of freedom. Our measurement model identifies the internal electronic
Value of NMR relaxation parameters of diamagnetic molecules for quantum information processing: optimizing the coherent phase
Quantum computing is the science that studies the applications of quantum mechanics in computer science. Thus, a quantum computer is an entity which can store quantum information, which in turn is an
Overcoming experimental limitations in a nonlinear two-qubit gate through postselection
TLDR
A modular-value two-qubit gate is introduced and its advantages in experimentally limited situations are explored, including the connection to a postselected cross-phase modulation scenario when a undesired absorption is present.
Quasiprobability behind the out-of-time-ordered correlator
Two topics, evolving rapidly in separate fields, were combined recently: the out-of-time-ordered correlator (OTOC) signals quantum-information scrambling in many-body systems. The Kirkwood-Dirac (KD)

It has been shown that observations of weak values outside the eigenvalue range of the corresponding operator defy classical explanation in the sense of requiring contextuality [M. F. Pusey,

Superposition, arguably the most fundamental property of quantum mechanics, lies at the heart of quantum information science. However, how to create the superposition of any two unknown pure states
Super-quantum discord in ferromagnetic and antiferromagnetic materials
TLDR
The temperature behavior of the super-quantum discord for two real magnetic materials is studied to predict quantitatively in advance the advantages of use of weak measurements versus projective one for quantum technologies in real settings where quantum discord is used as resource.

Liquid-state nuclear magnetic resonance as a testbed for developing quantum control methods
TLDR
This article summarizes work in implementing two complementary approaches to control qubit registers with liquid-state NMR methods that form a basis to design quantum-control methods for a block-architecture QIP so that large system size is not a barrier to implementing optimal control techniques.

Ensemble quantum computing by NMR spectroscopy
TLDR
A new computational model is presented, which differs from a QC only in that the result of a measurement is the expectation value of the observable, rather than a random eigenvalue thereof, which can solve nondeterministic polynomial-time complete problems inPolynomial time.

Experimental implementation of heat-bath algorithmic cooling using solid-state nuclear magnetic resonance
TLDR
It is demonstrated the repeated repolarization of a particular qubit to an effective spin-bath temperature, and alternating logical operations within the three-qubit subspace to ultimately cool a second qubit below this temperature, an important step forward in the manipulation of solid-state nuclear magnetic resonance qubits.

TLDR
In an implementation of Hardy's paradox, weakly measure the locations of two photons, the subject of the conflicting statements behind the paradox, and the resulting weak probabilities verify all of these statements but, at the same time, resolve the paradox.

TLDR
The dynamics of spontaneous emission offer a broader view of the measurement process than is usually considered within the weak measurement formalism and opens the path for the use of atoms and atomlike systems as sensitive probes in weak measurements, one example being optical magnetometry.
