Quantum physics reveals that the world has much more to offer than meets the eye. It explores the fascinating domain of the tiniest constituents of matter – electrons, photons and atoms – which defy the laws of classical physics and exist in a realm of possibilities rather than certainties. Only through observation or interaction with a system does one of these possibilities become an actual, measurable state. Quantum physics teaches us that nature is not fixed but governed by probabilities. It replaces the predictability of classical physics with a universe where chance, superposition, entanglement and uncertainty are fundamental principles. These findings sparked a profound revolution in our understanding of space, time and the very nature of reality.                   

As abstract as the quantum world may seem, it has long influenced our daily lives. Technologies such as lasers, computer chips, LEDs, MRI scanners and atomic clocks – essential for GPS – all rely on the principles of quantum physics. Now, a second quantum revolution is underway, paving the way for quantum computers, tamper-proof communication and next-generation quantum cryptography – technologies that research teams at the University of Vienna are helping to advance.

The obverse of Quantum Physics features Schrödinger’s cat, the thought experiment illustrating quantum superposition. The cat’s face dominates the niobium core, its eyes representing the superposition of the states ‘alive’ and ‘dead’. Around the cat, extending to the edge of the coin, are an unstable atom, a Geiger counter scale, a radioactivity symbol and the observer. The abbreviation of Schrödinger’s equation can be seen at the top of the coin.

The coin’s reverse celebrates Anton Zeilinger’s experiment on quantum entanglement. The simplified experimental set-up shows the measuring stations ALICE (A) and BOB (B), which are connected via a quantum channel and a classical channel. The niobium core illustrates the entanglement of two particles with opposite spin directions.

Great pillow
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
This pillow is great. It supports my head and is just the right softness. Love the fact that it is machine washable. Would definitely purchase it again.

Very well made pillow! It doesn't go flat right away like so many other pillows do. Very comfortable as well. I would purchase again.

Would buy again
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
I bought these pillows with the pillow protectors included. After 15 minutes of fluffing the pillows in the dryer they took their shape and were ready to use.

Nice medium thickness. Fits in shames great. Firm for a medium but will work well
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
Nice pillows for the price. I got the medium thickness and it’s a little stiff, but I think once slept on, it should soften up a bit, but if you like a softer or flatter pillow, definitely go for the soft one. But the quality seems to be very well-made. It puffed up straight out of the package. It didn’t have any smell whatsoever, and it fit perfectly in my standard size shams.

Loved them but may not last too long
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
I’m kind of torn on these. I love them and I want to buy more because they were very affordable and very comfy! I’ve had them less than six months and they lose their plumpness after a few nights sleep but they are easy to fluff back up. They are pretty thick and firm but form to your head and neck perfectly..for me at least. I’ve tossed them in the washer and dryer and they have been fine. Fluffed right back up perfectly. The material inside seems to be clumping together now. it’s easy to fluff them back out but you can notice the spaces where they’re starting to clump and even though they can be fluffed again it does seem they are starting to become compacted and I find myself having to fluff them more often. I’ll see how much longer they’ll last, but I will buy again because they are pretty comfortable. I love the covers they came with also. They stay cool and wash easy! Overall, great for the price, maybe not in the long run if you continue to buy, but I’ll see how much longer they’ll stay in good shape!
