Quantum simulators get error bars
Researchers have developed a method for determining the accuracy of quantum simulations. The new method not only reconstructs the dynamics of a quantum system from experimental data, but can also quantify the uncertainty of the predictions derived from it. The verification method was demonstrated in Innsbruck, Austria, on an ion-trap quantum computer with up to 51 qubits.
Not all quantum measurements are created equal
Proving that one quantum measurement is more powerful than another has long been difficult. Physicists from Heinrich Heine University Düsseldorf, Lund University, and the University of Innsbruck have now developed and demonstrated a simple technique to certify that a certain class of measurements has properties that cannot be mimicked by simpler means.

It can be used to identify critical error sources —a key to developing more robust, fault-tolerant quantum processors.

Entanglement characterization touches a new milestone
Entanglement is the backbone of quantum information science. Quantum computers and simulators can outperform classical calculations when simulating complex many-body quantum states. In modern times, characterizing entanglement in quantum simulations is a tricky task. Due to the fragile nature of entanglement and the exponentially increasing number of measurements required for characterizing entanglement with the system sizes, experimental techniques and analysis methods need to be upgraded to more sample-efficient methods. Here, theoretical ideas originally formulated for conformal field theories come into play. These ideas state that a mixed state, segregated from continuum spatial and temporal systems, can be represented by a Gibbs ensemble. The original concept was formulated for lattice models and has now been tested on a trapped ion quantum simulator.

Nuclear alchemy with antimatter
The study of radioisotopes in charged particle traps is a very active field in nuclear physics research.

The innovative method promises quantum sensors whose precision reaches close to the limit set by the laws of nature.
Position measurement of a dipolar scatterer via self-homodyne detection
The study of levitated dipolar scatterers is a growing field of physics that promises to uncover the connection between quantum mechanics and gravity and develop future devices for ultra-precise force sensing. In collaboration with the nanosphere team of the QI group, we investigated a new method based on the manipulation of spontaneous emission to measure the position and motion of these scatterers. In this work, we predict that our method, unlike other state-of-the-art techniques, can reach the Heisenberg limit of detection, in which the position measurement is only bounded by the recoil force of the scattered light.

Hence, this method witnesses the presence of useful entanglement. Their findings on this ‘verification without knowledge’ has been published in Nature Physics.

The results of our work are published in the journal Nature Photonics.

Such information could then be sent over optical fiber to a distant atom.

Universal digital quantum simulation with trapped ions
The time evolution of a quantum system under the action of a Hamiltonian acting for a duration t can be simulated by a gate-based approach. Instead of trying to engineer the Hamiltonian of interest as it is done in the analog quantum simulation approach, the digital method is based on sequences of quantum gates that generate the same propagator as the Hamiltonian to be simulated for a given instance of time. By making use of the Trotter formula, very different Hamiltonians can be simulated with the same basic universal set of quantum gates as we demonstrated in an experiment with two to six ions.

Deterministic entanglement swapping
Entanglement—once only a subject of disputes about the foundation of quantum mechanics—has today become an essential issue in the emerging field of quantum information processing, promising a number of applications, including secure communication, teleportation and powerful quantum computation. Therefore, a focus of current experimental work in the field of quantum information is the creation and manipulation of entangled quantum systems. Here, we present our results on entangling two qubits in an ion-trap quantum processor not through a direct interaction of the ion qubits but instead through the action of a protocol known as entanglement swapping.
Towards fault-tolerant quantum computing with trapped ions
Choosing the rules of quantum physics as the physical basis for constructing models of computation allows for solving certain computational problems more efficiently as in models based on classical physics. In the quantum circuit model, information is encoded in quantum bits and manipulated by applying appropriate quantum operations acting on the joint state space of the qubits. Similar to what is done in classical computation, these quantum operations can be decomposed into a sequence of gate operations, consisting of single-qubit operations and entangling operations acting on pairs of qubits.

Long lived entanglement
Arbitrary atomic Bell states with two trapped ions are generated in a deterministic and preprogrammed way. The resulting entanglement is quantitatively analyzed using various measures of entanglement. For this, we reconstruct the density matrix using single qubit rotations and subsequent measurements with near-unity detection efficiency. This procedure represents the basic building block for future process tomography of quantum computations.
