HOBBY: Computing, as in building computers, repairing, and any electronics. Never toss an electronic or computing component even if deader than the proverbial doornail. My husband is the expert. I’m trying to learn.
WHAT: Light-emitting diodes (LED) pre-cut (or before sizing) in/on a breadboard. Yes, shallow depth of field. By choice!
FOCAL POINT: Third from left LED in front row.
LIGHTING: Components are in a soft box lighted on two sides by standing Photogenic StudioMax lights triggered by an off-camera SB 800 strobe at 1/64 power.
SIZE: The breadboard (base with holes) measures 2 in / 5.08 cm), and with the negative/unused space equals about 2.5 in / 6.35 cm.
The height including negative/unused space measures 1.75 in / 4.45 cm.
Thanks for looking!

Research from QphoX, Rigetti, and Qblox Demonstrating Optical Readout Technique for Superconducting Qubits Published in Nature Physics
GlobeNewswire
DELFT, The Netherlands and Berkeley, Calif., Feb. 11, 2025 (GLOBE NEWSWIRE) -- QphoX B.V., a Dutch quantum technology startup that is developing leading frequency conversion systems for quantum applications, Rigetti Computing, Inc. (RGTI.NaE) , a pioneer in full-stack quantum-classical computing, and Qblox, a leading innovator in quantum control stack development, today announced that their joint research demonstrating the ability to readout superconducting qubits with an optical transducer was published in Nature Physics.
Quantum computing has the potential to drive transformative breakthroughs in fields such as advanced material design, artificial intelligence, and drug discovery. Of the quantum computing modalities, superconducting qubits are a leading platform towards realizing a practical quantum computer given their fast gate speeds and ability to leverage existing semiconductor industry manufacturing techniques. However, fault-tolerant quantum computing will likely require 10,000 to a million physical qubits. The sheer amount of wiring, amplifiers and microwave components required to operate such large numbers of qubits far exceeds the capacity of modern-day dilution refrigerators, a core component of a superconducting quantum computing system, in terms of both space and passive heat load.
A potential solution to this problem may be to replace coaxial cables and other cryogenic components with optical fibers, which have a considerably smaller footprint and negligible thermal conductivity. The challenge lies in converting the microwave signals used to control qubits into infrared light that can be transmitted through fiber. This is where microwave-to-optical transduction comes into play, a field dedicated to the coherent conversion of microwave photons to optical photons. QphoX has developed transducers with piezo-optomechanical technology that are capable of performing this conversion, forming an interface between superconducting qubits and fiber-optics.
To demonstrate the potential of this technology, QphoX, Rigetti and Qblox connected a transducer to a superconducting qubit, with the goal of measuring its state using light transmitted through an optical fiber. The results of this collaborative effort have been published in Nature Physics. Remarkably, it was discovered that not only is the transducer capable of converting the signal that reads out the qubit, but that the qubit can also be sufficiently protected from decoherence introduced by thermal noise or stray optical photons from the transducer during operation.
"Microwave-to-optics transduction is a rapidly emerging technology with far-reaching implications for quantum computing. Our work demonstrates that transducers are now ready to interface with superconducting qubit technology. This is an exciting and crucial demonstration, with the potential for this technology being far reaching and potentially transformative for the development of quantum computers,” says Dr. Thierry van Thiel, lead author of the work and Lead Quantum Engineer at QphoX.
“Developing more efficient ways to design our systems is key as we work towards fault tolerance. This innovative, scalable approach to qubit signal processing is the result of our strong partnerships with QphoX and Qblox and showcases the value of having a modular technology stack. By allowing our partners to integrate their technology with ours, we are able to discover creative ways to solve long-standing engineering challenges,” says Dr. Subodh Kulkarni, Rigetti CEO.
“Realizing industrial-scale quantum computers comes with solving several critical bottlenecks. Many of these lie in the scalability of the readout and control of qubits. As Qblox is entirely focused on exactly this theme, we are proud to be part of this pivotal demonstration that shows that QphoX microwave-to-optical transducers are a solid route to scalable quantum computing. We look forward to the next steps with Rigetti and QphoX to scale up this technology,” says Dr. Niels Bultink, Qblox CEO.

This is the hardware side of the NAS solution I was putting together before I came down with COVID. Will have that working shortly. This little computer compared with my very first PC here.

This began as a rather drab capture an hour or two before it rained in Jerusalem. In these parts, rain is a blessing! Some light texture was applied to the image.
The location is the UN tower hill overlooking the Old City. And yes, October is sliding towards November. Have a great day, one and all.
We use this machine at our research center to train deep neural networks and for other compute-intensive tasks.
That is some high tech right there.

Taken from Noonamah area at about 0300hrs today. Clouds backlit by lightning which was probably about 50Km east of Acacia Hills.
I was playing with a cloud and turned it black and white, then painted it, then combined it, then mosaicked it, played with the colours and ended up with this. I started with just white cloud through the middle and a light blue sky.
Petri Computor 35, with CC Petri 2.8/40 lens.
Compact camera, produced from 1970 until 1974. Clearly inspired by the Konica C35, so it has the programmed shutter and rangefinder focussing, but it differs in details. The exposure metering in not controlled by a needle displayed in the viewfinder, but by two lights (green/orange) for acceptable or risky shutter speeds. They are visible on top and in the viewer.
The film speed is set with a ring around the lens and not with a fiddly ring inside the filter thread. As the camera has no dial for exposure compensation, you can manipulate the exposure very quickly here.

A closer view of what sits on my desk in our office... Too see a wider angle view and more stuff Click Here, the description on the other photo also goes into much more detail about what I use and how I use it.
In short, about 5 years ago I uploaded a photo (now quite outdated) of what my desk looked like and the computing technology that I used... but now long overdue I have upgraded and replaced quite a bit. Things are now much simpler and easier to use... oh and I finally made the switch to Mac and have been loving life on OS-X.
What this photo shows is:
A 30" NEC monitor connected to an Apple Hex Core 3.33Ghz. Mac Pro w/12GB of RAM, dual 50GB OWC Solid State Drives(SSD), four 2TB Western Digital Black hard drives and a NewerTech eSATA card and two external 500GB Western Digital Studio Edition hard drives. The desktop has an Apple Wireless Keyboard, a Magic Trackpad and a Magic Mouse connected via Bluetooth and a Microsoft Ergonomic 4000 keyboard and a Microsoft LaserMouse6000 connected via USB2 sitting on a HumanScale 4G keyboard tray (it's designed for the Microsoft 'natural' form factor). Finally the Mac Pro has a Wacom Intuos3 tablet and a set of Klipsch ProMedia 2.1 speakers.
Laptop - An Apple 15" MacBookPro Core i5 2.4Ghz. notebook with 8GB of RAM and a 500GB Seagate MomentusXT hard drive (which also includes a 4GB SSD cache), with the upgraded high res. display. Attached is a 500GB G-Tech G-Drive Mini and a 1TB OWC Mercury Elite-AL Pro external drives connected via Firewire800 and an Apple MagicMouse via Bluetooth.

My Husband! Apparently slightly bored with wandering around the Sunflower Maze with me two weeks running and catching up on some emails on his iPhone. He had no idea I had taken this image until today :o)
I have quite obviously run some filters though this image and smoothed out the clouds a little so as to make it more of a concept image.
