Analytical and experimental study of center line miscalibrations in Mølmer-Sørensen gates
Fernando Martínez-García, Lukas Gerster, Davide Vodola +4
A major challenge for the realisation of useful universal quantum computers is achieving high fidelity two-qubit entangling gate operations. However, calibration errors can affect…
Experimental Bayesian calibration of trapped ion entangling operations
Lukas Gerster, Fernando Martínez-García, Pavel Hrmo +7
The performance of quantum gate operations is experimentally determined by how correct operational parameters can be determined and set, and how stable these parameters can be main…
Theory of versatile fidelity estimation with confidence
Akshay Seshadri, Martin Ringbauer, Jacob Spainhour +2
Estimating the fidelity with a target state is important in quantum information tasks. Many fidelity estimation techniques present a suitable measurement scheme to perform the esti…
Versatile fidelity estimation with confidence
Akshay Seshadri, Martin Ringbauer, Jacob Spainhour +3
As quantum devices become more complex and the requirements on these devices become more demanding, it is crucial to be able to verify the performance of such devices in a scalable…
Quantum portfolio value forecasting
Cristina Sanz-Fernandez, Rodrigo Hernandez, Christian D. Marciniak +5
We present an algorithm which efficiently estimates the intrinsic long-term value of a portfolio of assets on a quantum computer. The method relies on quantum amplitude estimation…
Demonstration of fault-tolerant universal quantum gate operations
Lukas Postler, Sascha Heußen, Ivan Pogorelov +10
Quantum computers can be protected from noise by encoding the logical quantum information redundantly into multiple qubits using error correcting codes. When manipulating the logic…
Characterizing quantum instruments: from non-demolition measurements to quantum error correction
Roman Stricker, Davide Vodola, Alexander Erhard +7
In quantum information processing quantum operations are often processed alongside measurements which result in classical data. Due to the information gain of classical measurement…
A universal qudit quantum processor with trapped ions
Martin Ringbauer, Michael Meth, Lukas Postler +4
Today's quantum computers operate with a binary encoding that is the quantum analog of classical bits. Yet, the underlying quantum hardware consists of information carriers that ar…
Optimal metrology with programmable quantum sensors
Christian D. Marciniak, Thomas Feldker, Ivan Pogorelov +7
Quantum sensors are an established technology that has created new opportunities for precision sensing across the breadth of science. Using entanglement for quantum-enhancement wil…
A compact ion-trap quantum computing demonstrator
Ivan Pogorelov, Thomas Feldker, Christian D. Marciniak +13
Quantum information processing is steadily progressing from a purely academic discipline towards applications throughout science and industry. Transitioning from lab-based, proof-o…
