A flexible electron interferometer demonstrating live phase imaging and interaction-free measurements

The resolution for imaging beam-sensitive materials, such as biomolecules, is limited due to high-energy electrons bombarding the sample, precluding imaging cellular dynamics or proteomics at the

Quantum state interrogation using a preshaped free electron wavefunction

: We present a comprehensive theory for interrogation of the quantum state of a two-level system (TLS) based on a free-electron – bound-electron resonant interaction scheme. The scheme is based on

Reduced damage in electron microscopy by using interaction-free measurement and conditional reillumination

Interaction-free measurement (IFM) has been proposed as a means of high-resolution, low-damage imaging of radiation-sensitive samples, such as biomolecules and proteins. The basic setup for IFM is a

Single Electron Interferometry: A Step Toward Quantum Electron Microscopy

Sub-angstrom resolved reconstructions of biological specimens could allow us to cure diseases, manufacture personalized pharmaceuticals, and understand biological mechanisms happening at the atomic

Attosecond electron pulse trains and quantum state reconstruction in ultrafast transmission electron microscopy

Ultrafast electron and X-ray imaging and spectroscopy are the basis for an ongoing revolution in the understanding of dynamical atomic-scale processes in matter. The underlying technology relies

Measurement of Temporal Coherence of Free Electrons by Time-Domain Electron Interferometry.

A time-domain interferometer is reported that measures and distinguishes the pure and ensemble coherences of a free-electron beam in a transmission electron microscope via symmetry-breaking shifts of photon-order sideband peaks and finds a substantial pure electron coherence connected to the thermodynamics of the emitter material and a lower ensemble coherence that is governed by space-charge effects.

Coherent properties of a tunable low-energy electron-matter-wave source

A general challenge in various quantum experiments and applications is to develop suitable sources for coherent particles. In particular, recent progress in microscopy, interferometry, metrology,

Transmission electron microscopy at the quantum limit

A number of visions for a new generation of dose-efficient electron microscopes have been advanced. These proposals, while inspired by quantum principles, make little contact with the broader field

Optical Excitations with Electron Beams: Challenges and Opportunities

Free electron beams such as those employed in electron microscopes have evolved into powerful tools to investigate photonic nanostructures with an unrivaled combination of spatial and spectral



Possible use of a Cooper-pair box for low-dose electron microscopy

A transmission electron microscope that takes advantage of superconducting quantum circuitry is proposed. The microscope is designed to improve image contrast of radiation-sensitive weak phase

A quantum mechanical scheme to reduce radiation damage in electron microscopy

We show that radiation damage to unstained biological specimens is not an intractable problem in electron microscopy. When a structural hypothesis of a specimen is available, quantum mechanical

Highly Coherent Electron Beam from a Laser-Triggered Tungsten Needle Tip.

An upper limit of the effective source radius is deduced both in laser-triggered and dc-field emission mode, which quantifies the spatial coherence of the emitted electron beam, revealing that the outstanding coherence properties of electron beams from needle tip field emitters are largely maintained in laser -induced emission.

Observation of the Kapitza–Dirac effect

The diffraction of free electrons from a standing light wave is reported—a realization of the Kapitza–Dirac effect as originally proposed.

Electron holography—basics and applications

Despite the huge progress achieved recently by means of the corrector for aberrations, allowing now a true atomic resolution of 0.1 nm, hence making it an unrivalled tool for nanoscience,

Quantum Zeno tomography

We show that the resolution ''per absorbed particle'' of standard absorption tomography can be outper- formed by a simple interferometric setup, provided that the different levels of ''gray'' in the

Noninvasive electron microscopy with interaction-free quantum measurements

We propose the use of interaction-free quantum measurements with electrons to eliminate sample damage in electron microscopy. This might allow noninvasive molecular-resolution imaging. We show the

Semitransparency in interaction-free measurements

We discuss the effect of semitransparency in a quantum-Zeno-like interaction-free measurement setup, a quantum-physics based approach that might significantly reduce sample damage in imaging and

Interaction‐free quantum measurements: A paradox?

In Heisenberg’s famous discussion of the measurement of a particle’s position using a microscope, the momentum transferred to the particle by the scattered photon makes the particle’s momentum
