text: We present an experimental demonstration of an impedance-engineered Josephson
parametric amplifier (IEJPA) fabricated in a single-step lithography process.
Impedance-engineering is implemented using a lumped-element series LC circuit.
We use a simpler lithography process where the entire device—impedance transformer
and Josephson parametric amplifier (JPA)—is patterned in a single electron beam
lithography step, followed by a double-angle Dolan-bridge technique for Al–AlOx–Al
deposition. We observe amplification with 18 dB gain over a wide 400 MHz bandwidth
centered around 5.3 GHz with added noise approaching the quantum limit, and a
saturation power of −114 dBm. To accurately explain our experimental results,
we extend existing theories for IEJPAs to incorporate the full sine nonlinearity
of both the JPA and the transformer. Our work provides a route to simpler realization
of broadband JPAs and a theoretical foundation for a regime of JPA operation that
has been less explored in literature.

text: We propose a simple method to measure nonlinear Kerr refractive index in mid-infrared
frequency range that avoids using sophisticated infrared detectors. Our approach
is based on using a near-infrared probe beam which interacts with a mid-IR beam
via wavelength-non-degenerate cross-phase modulation (XPM). By carefully measuring
XPM-induced spectral modifications in the probe beam and comparing the experimental
data with simulation results, we extract the value for the non-degenerate Kerr
index. Finally, in order to obtain the value of degenerate mid-IR Kerr index,
we use the well-established two-band formalism of Sheik-Bahae et al., which is
shown to become particularly simple in the limit of low frequencies. The proposed
technique is complementary to the conventional techniques, such as z-scan, and
has the advantage of not requiring any mid-infrared detectors.

text: "Over the past few years, the field of quantum information science has seen
tremendous progress toward realizing large-scale quantum computers. With demonstrations
of quantum computers outperforming classical computers for a select range of problems,1–3
we have finally entered the noisy, intermediate-scale quantum (NISQ) computing
era. While the quantum computers of today are technological marvels, they are
not yet error corrected, and it is unclear whether any system will scale beyond
a few hundred logical qubits without significant changes to architecture and control
schemes. Today's quantum systems are analogous to the ENIAC (Electronic Numerical
Integrator And Computer) and EDVAC (Electronic Discrete Variable Automatic Computer)
systems of the 1940s, which ran on vacuum tubes. These machines were built on
a solid, nominally scalable architecture and when they were developed, nobody
could have predicted the development of the transistor and the impact of the resulting
semiconductor industry. Simply put, the computers of today are nothing like the
early computers of the 1940s. We believe that the qubits of future fault-tolerant
quantum systems will look quite different from the qubits of the NISQ machines
in operation today. This Special Topic issue is devoted to new and emerging quantum
systems with a focus on enabling technologies that can eventually lead to the
quantum analog to the transistor. We have solicited both research4–18 and perspective
articles19–21 to discuss new and emerging qubit systems with a focus on novel
materials, encodings, and architectures. We are proud to present a collection
that touches on a wide range of technologies including superconductors,7–13,21
semiconductors,15–17,19 and individual atomic qubits.18\r\n"

text: 'Quantum entanglement has been generated and verified in cold-atom experiments
and used to make atom-interferometric measurements below the shot-noise limit.
However, current state-of-the-art cold-atom devices exploit separable (i.e., unentangled)
atomic states. This perspective piece asks the question: can entanglement usefully
improve cold-atom sensors, in the sense that it gives new sensing capabilities
unachievable with current state-of-the-art devices? We briefly review the state-of-the-art
in precision cold-atom sensing, focusing on clocks and inertial sensors, identifying
the potential benefits entanglement could bring to these devices, and the challenges
that need to be overcome to realize these benefits. We survey demonstrated methods
of generating metrologically useful entanglement in cold-atom systems, note their
relative strengths and weaknesses, and assess their prospects for near-to-medium
term quantum-enhanced cold-atom sensing.'

text: We present full-Maxwell topology-optimization design of a single-piece multilayer
metalens, about 10 wavelengths λ in thickness, which simultaneously focuses over
a 60° angular range and a 23% spectral bandwidth without suffering chromatic or
angular aberration, a “plan-achromat.” At all angles and frequencies, it achieves
diffraction-limited focusing (Strehl ratio >0.8) and an absolute focusing
efficiency of >50%. Both 2D and 3D axisymmetric designs are presented,
optimized over ∼105 degrees of freedom. We also demonstrate shortening the lens-to-sensor
distance while producing the same image as for a longer “virtual” focal length
and maintaining plan-achromaticity. These proof-of-concept designs demonstrate
the ultra-compact multifunctionality that can be achieved by exploiting the full
wave physics of subwavelength designs and motivate future work on design and fabrication
of multilayer metaoptics.

text: "Research in the field of colloidal semiconductor nanocrystals (NCs) has progressed
tremendously, mostly because of their exceptional optoelectronic properties. Core@shell
NCs, in which one or more inorganic layers overcoat individual NCs, recently received
significant attention due to their remarkable optical characteristics. Reduced
Auger recombination, suppressed blinking, and enhanced carrier multiplication
are among the merits of core@shell NCs. Despite their importance in device development,
the influence of the shell and the surface modification of the core@shell NC assemblies
on the charge carrier transport remains a pertinent research objective. Type-II
PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated,
still exhibit instability of their electron \r\n ransport. Here, we demonstrate
the enhancement of electron transport and stability in PbTe@PbS core@shell NC
assemblies using iodide as a surface passivating ligand. The combination of the
PbS shelling and the use of the iodide ligand contributes to the addition of one
mobile electron for each core@shell NC. Furthermore, both electron mobility and
on/off current modulation ratio values of the core@shell NC field-effect transistor
are steady with the usage of iodide. Excellent stability in these exclusively
electron-transporting core@shell NCs paves the way for their utilization in electronic
devices. "

text: We present the fabrication and characterization of an aluminum transmon qubit
on a silicon-on-insulator substrate. Key to the qubit fabrication is the use of
an anhydrous hydrofluoric vapor process which selectively removes the lossy silicon
oxide buried underneath the silicon device layer. For a 5.6 GHz qubit measured
dispersively by a 7.1 GHz resonator, we find T1 = 3.5 μs and T∗2 = 2.2 μs. This
process in principle permits the co-fabrication of silicon photonic and mechanical
elements, providing a route towards chip-scale integration of electro-opto-mechanical
transducers for quantum networking of superconducting microwave quantum circuits.
The additional processing steps are compatible with established fabrication techniques
for aluminum transmon qubits on silicon.
