The Future of Computing: Bits + Neurons + Qubits
D. Gil, W. Green·Nov 15, 2019
The laptops, cell phones, and internet applications commonplace in our daily lives are all rooted in the idea of zeros and ones - in bits. This foundational element originated from the combination of mathematics and Claude Shannon's Theory of Informa...
A unidirectional on-chip photonic interface for superconducting circuits
P. Guimond, P. Guimond, B. Vermersch +10 more·Nov 6, 2019
We propose and analyze a passive architecture for realizing on-chip, scalable cascaded quantum devices. In contrast to standard approaches, our scheme does not rely on breaking Lorentz reciprocity. Rather, we engineer the interplay between pairs of s...

Jianwei Wang, F. Sciarrino, A. Laing +1 more·Oct 21, 2019
Quantum technologies comprise an emerging class of devices capable of controlling superposition and entanglement of quantum states of light or matter, to realize fundamental performance advantages over ordinary classical machines. The technology of i...
Challenges and Opportunities of Near-Term Quantum Computing Systems
A. Córcoles, A. Kandala, Ali Javadi-Abhari +6 more·Oct 7, 2019
The concept of quantum computing has inspired a whole new generation of scientists, including physicists, engineers, and computer scientists, to fundamentally change the landscape of information technology. With experimental demonstrations stretching...
Error detection on quantum computers improving the accuracy of chemical calculations
M. Urbánek, B. Nachman, W. D. de Jong·Sep 30, 2019
Author(s): Urbanek, M; Nachman, B; De Jong, WA | Abstract: © 2020 American Physical Society. A major milestone of quantum error correction is to achieve the fault-tolerance threshold beyond which quantum computers can be made arbitrarily accurate. Th...
Classical algorithms for quantum mean values
S. Bravyi, David Gosset, R. Movassagh·Sep 25, 2019
Quantum algorithms hold the promise of solving certain computational problems dramatically faster than their classical counterparts. The latest generation of quantum processors with ~50 qubits are expected to be at the brink of outperforming classica...
Optimal preparation of the maximally entangled W state of three superconducting gmon qubits
Dalton Jones, Armin Rahmani·Sep 20, 2019
Superconducting gmon qubits allow for highly tuneable quantum computing devices. Optimally controlled evolution of these systems is of considerable interest. We determine the optimal dynamical protocols for the generation of the maximally entangled W...
Quantum computing with multidimensional continuous-variable cluster states in a scalable photonic platform
Bo-Han Wu, R. N. Alexander, Shuai Liu +1 more·Sep 12, 2019
Quantum computing is a disruptive paradigm widely believed to be capable of solving classically intractable problems. However, the route toward full-scale quantum computers is obstructed by immense challenges associated with the scalability of the pl...
Noise-robust exploration of quantum matter on near-term quantum devices
J. Borregaard, M. Christandl, Daniel Stilck Francca·Sep 10, 2019
We describe a resource-efficient approach to studying many-body quantum states on noisy, intermediate-scale quantum devices. We employ a sequential generation model that allows to bound the range of correlations in the resulting many-body quantum sta...
